The "Robo-Kitty 3000," AKA the "Supa-Mecha Kitty 3000," is a giant, robotic cat made by the evil Dr. Dilbert "Dinkle" and is operated by Petey. It only appeared in the book, Super Diaper Baby 2 The Invasion of the Potty Snatchers. "Rip Van Tinkle" used scrap metal to build the Robo-Kitty 3000. Also, it took 24 hours to build. It was used to destroy toilets. Petey's Robo-Kitty 3000 also was used to steal all of the diapers in Piqua, Ohio. Later, Petey's Supa-Mecha Kitty 3000 was used to fight Billy and Diaper Dog. The robot also makes a cameo appearance in Mothering Heights.
