Rapeville State Penitentiary is the prison Mr. Larrity tricked his empoyees into going to in the episode Super Prison Breakout. It is controlled by Warden James Tiberius Shank, a personal friend of Mt. Larrity. Shank dreamed of transforming the prison into a theme park (Prisonland).
The prison hosts a number of extremely dangerous criminals, many of which the GamaVisio staff was personally introduced to.
