These are notes regarding the differences from the official episode script and what appeared in the finished episode.
- There’s no mention of Chance’s arm stripes needing to be missing for whatever reason, meaning this is in fact an error. An especially egregious one, considering how well animated the episode is otherwise.
- The obstacle course’s location in the salvage yard is given as being in “the backlot.” Although presumably this means somewhere behind the garage, in the background art, it appears as though it’s more to the side (which side, though, I couldn’t say).
- I’ve always been a little uncertain about exactly what it is Chance falls into. Due to the color, I assumed it was either oil or water with an oil slick on top. Leopold just calls it “a pond.” This suggests it’s a natural pond and not one Chance and Jake dug for the obstacle course. Weirdly, it comes out of nowhere; maybe I’m just really tired, but I’m pretty sure Leopold doesn’t mention it until Chance falls into it.
- What Chance and Jake swing over the pond on are referred to as bungee cords, which is an odd choice for something to have them swing on, given bungee cords’ elasticity. You’d think their weight would pull the cords down and they’d just hit the ground, and in addition they’d stand less chance of breaking the way Chance’s does. In the episode, I’m pretty sure they just swing on normal ropes.
- Jake doesn’t make it to the finish line. He stops short of it and runs back to help Chance after realizing he isn’t faking. This means neither SWAT Kat wins the race. I wonder if him making it to the finish line and then going back for Chance was something someone suggested so one of the SWAT Kats would win.
- Jake seems a little more suspicious about Chance’s claim that the reason he sank was because of a cramp.
- Slightly different dialogue: Jake says “No sweat” instead of, “Hey, don’t sweat it.”
- The homeless kat is introduced as “a street person” but afterwards referred to as “an alleykat.”
- The Erlenmeyer flask Dr. Viper is holding is incorrectly called a beaker. This is a mistake made commonly in fiction. SWAT Kats does it a lot (for example, in both the script and model sheets for Destructive Nature, what is obviously a flask is called a beaker). Apropos of nothing, considering Erlenmeyer flasks are named for Emil Erlenmeyer, I wonder if that’s who Emil the guard in The Origin of Dr. Viper is named after.
- Katalyst X-63 is alternately referred to as either Katalyst M63K or Katalyst 500 throughout the script. At first I thought there were two katalysts (with Katalyst M63K being what Viper pours on the animals in the pet store, and Katalyst 500 being the bulk of the mutagen flooding the city, which would make sense because the two are colored differently and apart from that one tree, the main bulk of the stuff flooding the city doesn’t mutate anything, but Leopold clearly just couldn’t make up his mind which name he liked better while writing… or forgot that he’d already named the stuff Viper was used Katalyst M63K when he has it referred to as Katalyst 500 later.
- The frog Viper mutates is in a bowl, not a terrarium.
- The scene of the alleykat being killed is absent from the script. The scene simply cuts to Manx getting in the shower.
- Manx’s bathroom has a tub instead of what is clearly a walk-in shower.
- Leopold is maddeningly vague about exactly where the scene of Manx preparing to take a shower is taking place. Obviously, it’d be in a bathroom, but he never calls it that. The only time the word “bathroom” is used is when Manx grabs the phone, described as a wall-mounted bathroom phone. Also, when he yells for help, Leopold doesn’t describe his tail frizzing up. Since the alleykat being attacked by the tentacle doesn’t happen in the script, this means the only two scenes in the entire show where kats’ tails frizz up are not in the script at all. Likely this was a detail added by either the storyboard artists or the animators.
- The scene of Callie driving and then contacting the SWAT Kats happens differently. She calls them while still in her car, not after she gets out due to the vehicle sinking. The car is still hit with a sudden tidal wave of ooze and begins sinking, so she gets out, but this happens after she calls the SWAT Kats, not before.
- Slightly different dialogue from Chance: “Come on, bud, can’t you kick harder than that?” as opposed to “Come on, bud, can’t you hit harder than that?”
- Extra dialogue from Callie explains that she barely escaped from her apartment. This means firstly that we now know she lives in an apartment building, assuming we take this dialogue as canon, meaning we know she and Feral live in apartments while Manx lives in a mansion. This also means Callie got into her car and tried driving somewhere as opposed to already being out driving and caught by surprise.
- Callie’s apartment building is actually described and shown to be filling up with the mutagen-tainted water. At first I thought this was odd, because it would be impossible for the water to be so deep the entire building is submerged but also shallow enough that Callie can drive through it. But then it occurred to me that the mutagen wasn’t flowing up through the building’s interior, but rather down through it from burst pipes and faucets, like in Manx’s shower.
- Different dialogue from Callie: ” Downtown has been evacuated. I’m meeting the Mayor and Commander Feral at Enforcer Headquarters!”
- The tree that attacks Callie mutates differently. The way Leopold describes it, the tentacle-like branches are more octopus-like with suckers as opposed to vine-like with horns.
- Felina rescues Callie with a rope as opposed to a rope ladder.
- The scene where Felina pulls her laser pistol and shoots over Callie’s shoulder happens differently, presumably because, as Mutation City was written as the second episode of the second season, not the first, this was not originally intended to be the character’s introduction. There’s no brief moment where we’re made to think she’s aiming at Callie only to fire over her shoulder. She says “Not a good night to be out the streets, Deputy Mayor!” before drawing her gun, not after; she says the line, then sees the branch, draws and fires. In this version, it is thus clear from the get-go Felina is on Callie’s side and there’s no fakeout. I assume the fakeout was added when it was decided Mutation City, not A Bright and Shiny Future, would be episode one of season two, and having it look like Felina was about to shoot Callie before firing over her shoulder instead was the only way they could think of to have her introduction leave any kind of impression. As I’ve often said, Mutation City was a weak introduction to Felina.
- There’s no indication give that the frog that attacks the Turbokat is the same one we first saw get mutated at Pet World. This makes since, because there’s nothing in the finished episode to suggest it either. Especially since there are multiple giant frogs throughout the episode.
- Deleted scene: As T-Bone pushes the throttle forward to make the Turbokat go faster to try and dislodge the frog monster, he and Razor activate electrified “pressure suits” to help them withstand the G-forces. I’m not entirely sure what them being electrified has to do with anything. In any case, this scene, and this entire element of their flight suits, was obviously dropped completely. Razor also has a deleted line here: “Pressure suits activated.” This feature is only mentioned once more in the script.
- The glass of the cockpit canopy is described as being weakened by the acidic saliva of the frog, suggesting that it’s ordinarily supposed to be more strongly reinforced and that without the acid, the frog’s tongue wouldn’t have been able to smash through the top.
- The top-mounted missile launcher thing that finally dislodges the frog and sends him shooting forward is just called “a missile launcher.” It’s also only one launcher and one missile, not two launchers and two missiles.
- As the frog is flying towards Enforcer Headquarters, Razor actually tries to avoid having it crash into the building by having the (nondescript) missile (“Guess I better let froggy go!”), but of course even after being released from the missile’s grip, the monster still crashes into the side of the building above the runway. I kinda prefer this as it shows Razor at least trying to avoid causing any damage to the building, whereas in the episode, it seems like neither he nor T-Bone care that the frog hits the building beyond T-Bone mentioning that it happens. Though this makes it odd Razor doesn’t defend himself when Feral gets angry at him for it, since he could say he tried to prevent it and be telling the truth. The frog also lands differently, taking out some parked Enforcer choppers (rather like the Turbokat did when it crashed on the Enforcer runway in Enter the Madkat).
- Feral walks to the downed frog first and not kind of over to the SWAT Kats, then to the frog. Felina’s dialogue here is also a little different: “Didn’t Dr. Konway say he wanted a live specimen to examine?” as opposed to “Dr. Konway did say he wanted a live speciment to examine,” changing her line from a rhetorical question to a statement.
- Extra dialogue from Feral: “Back off, everybody. I can handle this.” In an interesting bit, he protectively waves not only Felina back away from danger, but the SWAT Kats as well. He then is described as walking over to the frog (even though he already did that!). What he’s intending to do, I don’t know, but T-Bone’s line (“Don’t get any warts, Commander.”) distracts him from doing it, which – and I never thought about this until now – means T-Bone basically almost accidentally gets Feral killed because it’s Feral turning to glare at him for that crack about not getting warts that gives the frog time to regain consciousness, sit up and attack him.
- Feral is described as almost being grabbed by the frog’s tongue and diving aside to safety, which I don’t remember happening in the episode. He’s just gone from the shot as the net and gas grenade hit the creature.
- Feral isn’t described as being annoyed at T-Bone’s comment that Felina is “pretty quick on the draw.”
- The two sergeants Feral talks to are just called “Enforcer #1” and “Enforcer #2.” The kind of Enforcer they are isn’t specified.
- In the episode, the two sergeants run off and the scene fades to the lab. Here, though, Feral makes a point of grabbing Felina’s arm and steering her away from the SWAT Kats. Then the scene fades out.
- The device Dr. Konway uses to study the mutagen is described thusly: “A high-tech scanner” that uses a rotating “kat-scan-type barrel device” to examine the mutagen sample in the petri dish (which Leopold calls “a bowl”). Wires connect the “kat-scan-type barrel device” to a “digitized TV monitor” which shows a blown up image of the sample. What Leopold is describing is an electron microscope. I have no why he had to over-complicate the description so much, but, considering he calls flasks beakers, I’m assuming he knows what an electron microscope is but not what it’s called, or didn’t at the time he wrote this. That, or he assumed the storyboard artists and animators wouldn’t know what an electron microscope was and do described what one looks like as best as he could.
- In the episode, we see cells on the screen, making Dr. Konway’s line about “DNA strips” kind of odd. Here, though, DNA helixes are explicitly described, meaning Konway’s line is an artifact of a version of the scene where the screen magnified the image of the mutagen sample a lot more.
- Speaking of Dr. Konway, he’s introduced a bit oddly. Leopold introduces him as “Dr. Konway (that’s what his nameplate says),” as though that’s an unusual name and nobody would believe it unless they read his nametag. As it is, although he is wearing a lamenated Enforcer ID badge in the episode, it’s never shown in enough detail to show if it actually does say “Dr. Konway,” but I’ll take Leopold’s word for it. Konway is specifically described as “a bio-tech specialist.” So now, like Dr. Greenbox (at least in Chaos in Crystal), we know his exact profession beyond just being a scientist.
- Not a difference, but Manx is described as nervously tugging on Konway’s sleeve as he talks to him. And, sure enough, he does in the final episode, a little detail I never noticed.
- The cage seen in background artwork was originally going to factor into the plot. The frog is imprisoned inside it. Whereas in the unused background art, it’s just a regular cage, the script called it “a laser-barred cage.” I had thought there’d be a scene of the frog being removed from the cage and placed on the examination table, but the table is completely absent from the scene and was something added later; the frog remains in the cage when Konway feeds it the antidote and returns it to normal. I’m not sure why this change was made, since even though it’s out cold, it still seems a little irresponsible of the Enforcers to have the creature lying on the big table unsecured in any way. The cage (with laser bars or otherwise) seems much more practical.
- Konway does some more messing around with test tubes before telling Feral he needs more anti-mutagens, as opposed to just walking to the window while still holding the petri dish.
- Somewhat different line from Manx: “B-But that’s miles away. Right in the center of my slime cover city.” Two sentences rather than one, along with a vague indication of Megakat Biochemical Labs’ distance from Enforcer Headquarters.
- Somewhat different line from Feral: “No problem, Mayor.” As opposed to, “Don’t worry, Mayor.”
- Rather than joking about “not breaking any laws,” Razor jokes about “not stepping on his tail,” in reference to disobeying Feral.
- T-Bone is a little more persuasive towards Manx here: Instead of just going “Of course, if the Mayor ordered us to help…” and trailing off (apparently intending to let Manx come to the conclusion himself), he adds, “I guess we’d have to. As civic-minded citizens.”
- Manx’s objection to the idea of going behind Feral’s back and telling the SWAT Kats to go despite what Feral said is a little more nuance. He doesn’t just stammer “Commander Feral did say…” Well, he does, but it is prefaced with, “Uh, er, I’m not sure that’s correct politically, Callie.” By which I think he means countermanding the Enforcer commander’s orders would be him overstepping his authority and hurt his chances at re-election, as opposed to the usual meaning of “politically incorrect.”
- When telling the SWAT Kats to go, Manx’s line is the same, but, picking on T-Bone’s line (“If the Mayor ordered us to help…”), he adds, “…and that’s an order.”
- Deleted dialogue from the SWAT Kats: T-Bone says “We’ll do our best, Mayor,” and Razor adds, “Roger that.”
- When telling the pilot he initially doesn’t know is Felina (which I always thought was odd; he doesn’t recognize his niece when the only thing disguising her is that she has her visor down?) to fly him to Megakat Biochemical Labs, Feral points out the windshield. I guess this was dropped because him pointing would make it seem like he assumes whoever is serving as his pilot is a moron and doesn’t know where Megakat Biochemical Labs is.
- The line “Megakat Biochemical. 8 miles and closing” is spoken by Feral, not Felina.
- The mutant tentacles are just called… “mutant tentacles.” Yeah, this was written in a hurry. Leopold isn’t really too creative with the monster names here. It reminds me of how he calls the three-headed monster in Succubus! the “tri-head.”
- After Feral and Felina’s chopper is downed, one of the frog monsters is described as grabbing Felina’s laser pistol from her hand, but isn’t described as eating it as in the episode.
- Deleted Scene, Part 1: Instead of immediately being pulled under by the “scum-snake,” the SWAT Kats try to help Feral and Felina by attacking the frogs with “Stapler Missiles.” These basically function like two-pronged Octopus Missiles, or rather a variation on the Pincer Missile from Bride of the Pastmaster. The frogs get pinned (harmlessly) to the side of a building, a bank called First Megakat Savings (it’s interesting how there’s more of the SWAT Kats non-fatally taking out the mutated animals here in the script as opposed to them just blasting them to bits in the finished episode). In hindsight, this scene shouldn’t have been cut. Since without it, the mutated frogs just disappear, and after Feral and Felina get swept off the top of the floating chopper they should be in the water with them and thus in danger, but this is ignored, and the two are later being attacked by a different monster entirely.
- Deleted Scene, Part 2: T-Bone lands the Turbokat on the surface of the water using Turbo-Pontoons, which are, well, I dunno what’s “turbo” about them, but they’re pontoons that deploy from the bottom of the jet and allow it to float like a seaplane. His intention is to pick up Feral and Felina, presumably to either bring them with him and Razor to Megakat Biochemical Labs or fly them back to Enforcer Headquarters, then resume their mission to get the anti-mutagens. How this would work, I’m not sure. Probably they would’ve ended up in the bomb bay like Dr. Sinian and Henson in The Deadly Pyramid. In any case, Felina has a deleted bit of dialogue here: “C’mon, Uncle. Looks like we’ve got a ride… and not a minute too soon.” What she means is the captured frogs are using their acid spit to melt the Stapler Missiles pinning them to the bank. Only then does the “scum-snake” pull the Turbokat under, and the scene proceeds as it does in the finished episode (minus the added difference of the captured frogs threatening to break free).
- Deleted Scene, Part 3: As Viper pours the katalyst on himself, the frogs finish breaking free from the Stapler Missiles. It’s one of these critters that eats the empty flask (though it grabs it with its tongue rather than just open its mouth and lunging forward to swallow it). Interestingly, the frogs are described as following Viper as he swims away, a detail added presumably to explain why the floundering Feral and Felina won’t be in any more danger from them and be seen getting menaced by a different creature later.
- Oh, Mr. Leopold. After all these years of wondering what the octopus-like but bizarrely-named “scum-snake” is actually called… all we get is that it’s “a hideous creature” and “a mutation.” We’re not even given an indication of what it used to be. Leopold really wasn’t bringing his A-game to this one. It’s possible these various monsters received proper names in the model sheets, but, of course, we lack access to those at present and likely will never see them, as the only model sheet that exists from this episode is one for Dr. Konway. That said, when another one of the same kind of creatures appears, Leopold does give the thing the more apt name of “a giant one-eyed squid.”
- The reason for the electrified pressure feature on the flight suits is not given a Watsonian (i.e., in-universe) explanation, but it does have a Doylist (out-of-universe) one: to add extra danger as the cockpit floods, with the danger being not only that the SWAT Kats might drown but that they might get electrocuted. This was wisely dropped as I still can’t figure out why their flight suits being electrified would protect them in the manner Leopold describes. It was just done to add the danger of being electrocuted. Though oddly neither SWAT Kat comments on it here; in fact, now that I think about it, the suits being electrified makes Razor’s suggestion that they eject (underwater!) seem really dumb, and T-Bone seem less like he’s afraid of the water and more like he’s being smart and not going swimming in clothes that could fry him.
- Finally, a proper name for one of these creatures! The thing menacing Feral and Felina is referred as a “slime snake.” When the slime snake (now I finally have something to call this particular monster!) lunges as its intended victims just as Feral and Felina are yanked up to safety, it just chomps down on empty air. The bit with it slamming face-first into the building would appear to be yet another detail added during the storyboard or animation phase.
- When Callie and Manx are talking to the SWAT Kats over what is definitively confirmed to be an Enforcer communicator (sorry, Mark, but you got that one way wrong back in that ’95 Animato! episode guide), the two guys standing in the room with them are to be “the two Enforcers from the roof,” i.e., Enforcer #1 and Enforcer #2, whereas in the finished episode, in the two scenes it’s two different pairs of guys: two sergeants on the runway and two commandos in the lab. I was hoping to see if the script had something to say about their visors being up, as this scene is the only time we see an Enforcer commando’s eyes, but chalk that to yet another decision likely made by the storyboarders.
- The two commandos who run out to greet Feral and Felina as the SWAT Kats set them down on the runway are also supposed to be two commandos from the lab; in a deleted bit, they’re described as hurrying from the room and then running outside. I had wondered by there were two random Enforcers in that scene with Callie and Manx, and this also explains why they disappear between shots; the bit with them leaving the room was deleted. Though this means that they made a point of lowering their visors to go greet the arriving Feral and Felina. Does this mean it’s against protocol for Enforcer commandos to have their visors up?
- Manx calls the mutagen-tainted water “this glop” instead of “this stuff.”
- When T-Bone mentions they used up all their fuel getting free, he doesn’t refer to the monster they were dragged under by as a “scum-snake.” He in fact doesn’t refer to the thing at all directly.
- Razor refers to the monsters as “slimeballs” instead of “scumballs.”
- After all these years, what do I find out the jetskis are called? “Jet-Skis.” Oh, Mr. Leopold. Don’t get me wrong, I’m enjoying the heck outta this script, but Glenn Leopold really seems like he’s phoning it in with the names of things.
- A deleted exchange between T-Bone and Razor as the ride through the flooded city: T-Bone cracks, “These jet-ski missiles fast enough for ya buddy?” Razor replies, “Yeah, but they don’t hold enough turbo-blades.” There’s a bit where they do fire some Turbo-Blades at the tentacles coming out of the buildings, as opposed to going directly for the Macro-Wave Blasters. Calling the jetskis “jet-ski missiles” reminds me of how the Cyclotron’s full name is the Cyclotron Missile. At this point, all I can figure is that any vehicle launched from the jet is automatically considered a missile as opposed to a deployed vehicle. And indeed, both the Cyclotron and these jetski things are indeed initially fired in missile form before turning into vehicles in mid-air.
- Running out of Turbo-Blades is why the SWAT Kats use their Macro-Wave Blasters. As mentioned, though, in the finished episode, I don’t remember them using Turbo-Blades and running out before switching to the blasters.
- Deleted Scene: Originally, the SWAT Kats were supposed to fight the second slime snake on their way to the lab, not just once. The scene involving the first one was deleted. In it, the creature attacks Razor from behind, and vomits acid puke at Razor, who deflects it using his Glovatrix’s retractable shield, while T-Bone, firing his Macro-Wave Blaster two-handed (“in a comic book action pose”), and shoots at it, but it dives under the surface. It then resurfaces ahead of Razor as and the scene continues as it does in the episode.
- In the episode, Razor vaults over the mutated snake through some unknown means. I had hoped that the script explain precisely how his jetski does this, but Leopold just says it does. Oh well.
- The snake’s tongue is described as “a tentacle” and it crushes T-Bone’s jetski rather than eating it. Since it doesn’t blow up inside the thing’s mouth, the monster isn’t killed.
- T-Bone is not described as losing his Glovatrix. The fact he does is something that goes by so quickly in the episode that it almost seems like it just disappears between shots. The fact Leopold doesn’t describe this happening but the storyboard artists and/or animators bothered including it tells me this script really was a bit of a rush job for him. It really doesn’t seem like anybody was very keen on making this one, judging by how little work seems to have gone into the script (that or Leopold was overworked as usual, since he basically carried half the frickin’ show entirely on his own, script-wise), making it ironic it’s such a beloved classic of the second season and the show overall.
- How Razor assembles his breathing apparatus (which isn’t given a specific name) is different. Instead of pulling the air tubes from his backpack and attaching it to his oxygen mask, the tubes are pulled from the mask and attached to the backpack.
- The thing that extends from Razor’s Glovatrix before he dives in is referred to as a “propulsor device,” and is what pulls him along through the water by his wrist.
- When Razor actives his helmet’s flashlight, it’s described as the triangle retracting upwards to reveal the lens of the flashlight, rather than the triangle just lighting up as in the episode.
- The little mutant that bites T-Bone is a tadpole, which explains why he specifically mutates into a frog monster.
- When Razor asks T-Bone if he wants him to drive, T-Bone replies “Very funny,” instead of “I’m fine.”
- As it turns out, the sign saying “Anti-Mutagent” is an error. The script correctly calls the laboratory the SWAT Kats enter “Anti-Mutagen Research.” Although its full name given here is “Anti-Mutagen Research Lab.” I don’t think it says “Lab” on the sign in the episode.
- T-Bone’s monster form is referred to as “a mutant version of himself,” and referred to as “the T-Bone Mutant.” Well, actually, T-Bone/Mutant, as though he’s half and half, which may have been what gave the Tremblays or whoever the idea to have only one side of his body mutated.
- Instead of jumping onto the jetski, Razor is thrown onto it by the T-Bone mutant. He also lands on his back and then stands up, as opposed to landing on his feet.
- The canon name for the weapon that launches the Octopus Missile is the very apt Octopus Missile Bazooka. It also is described as deplying differently; here, the front of the vehicle slides down forwards and it flies out, whereas in the episode the handlebar section slides back and up and the weapon flies out.
- Dr. Viper’s giant monster form is not described in any detail. He’s just said to be very big. It appears as if the original idea was for him to just be a giant version of himself with no differences apart from what I assume to be the self-evident fact he’d have ripped off his lab coat and thus be Dr. Viper but giant and naked. It doesn’t appear as if a specific look for his monstrous giant form had been decided at the time Leopold wrote the script.
- The way the T-Bone mutant is pinned to the wall by the Octopus Missile is described differently. Instead of being pinned by the torso, he appears to be pinned by the face like Dr. Street in The Ci-Kat-A, since he’s described as “glaring at Razor through the pincers.” It was likely changed so it’d look less painful.
- The giant Dr. Viper doesn’t knock an Enforcer chopper out of the air. Something else added during storyboarding, I guess.
- Feral isn’t supervising the rooftop laser batteries, but in a chopper personally attacking the giant Viper. Nothing comes of this. Leopold describes Feral’s chopper swooping in and Viper smacking the building with his tail, and then Razor shows up and Viper reacts, while Feral and his chopper just disappear from the scene completely.
- When Viper shoots acid from under his fingernails, the nails aren’t described as flipping up (one of the more unsettling visuals in the episode).
- Throughout the script, Leopold has used “claw” in place of “hand,” I should mention. Twice, the SWAT Kats’ hands gripping the Turbokat’s control stick or a weapon are referred to as their “claw,” singular, and it’s same here when Viper catches the falling anti-mutagen cannisters. This is very odd terminology as it makes everyone seem either like they’re just daintily using their fingernails or they all have lobster claws or something.
- Alternate dialogue from Razor: “One last chance before I ditch!” instead of “Gotta eject! Now’s my chance!” His targeting scope is described as having a night vision feature, but this was dropped for the episode as far as I can tell.
- Alternate dialogue: Razor says “Loaded, locked… launched!” instead of “Locked! Launch!”
- What happens to Dr. Viper is not described. As in the episode, he just kind of disappears.
- We finally now have an answer to what some of the different mutated animals are, as the “slime snakes” and “one-eyes” are described as reverting back into snakes, newts and goldfish. The newts appear to have been dropped, since in the finished episode we only see a frog, scum-snake and slime snake return to normal. It was always obvious what the frog and slime snake turned back into, but for years we never knew what the one-eyed, tentacled “scum-snake” thing was supposed to revert back to. Now we know. It was a fish. Well, at least some mysteries were solved!
- Razor’s line “Very funny” in response to T-Bone saying he wants flies for breakfast is missing. It was likely something Barry Gordon ad-libbed in recording.
