A maximum security prison is located. Mac and Molly Mange were sent there to serve out a nine life sentence and later escaped. Turmoil was later imprisoned in Alkatraz following her capture by the SWAT Kats.
In the unfinished episode Turmoil 2: The Revenge, Turmoil and her imprisoned crew would’ve escaped from Alkatraz using an intentionally started riot in the exercise yard as a distraction.
