The blueprint of this brain tank is encountered as a boss fight at the end of the Brain Tumbler Experiment which is used by the brain of Dogen instead of Oleander, however, the blueprints for it can be found at the end of Basic Braining. Razputin encounters another in the Thorney Towers Home for the Disturbed, operated by Oleander. Oleander's PSI powers are much more advanced than when he was in his human state. During the fight, Razputin's brain is sneezed out, and eventually makes its way to the tank, where it converges with Oleander's, creating the Meat Circus.
