Crazy Manny is the proprietor of a store bearing his name. In The Unconvincing Turtle Titan, he was mind-controlled by Dr. Malignus and forced to rob his own store, before he was stopped and snapped back to his senses by Michelangelo.
In The Golden Puck, Crazy Manny was providing three snowmobiles for a giveaway at a super slam hockey game. He was pleased by the lack of damage to the snowmobiles after the stadium was attacked, but was then dismayed by their theft by the Turtles.
