Captain Underpants Wiki

Super Diaper Baby 2 1/2 is a comic book made by George and Harold in Captain Underpants and the Tyrannical Retaliation of the Turbo Toilet 2000. The comic was

meant to be sold in Jerome Horwitz Elementary School and earn the boys enough money for snacks. It is a sequel to Super Diaper Baby 2: The Invasion of the Potty Snatchers and a crossover with Dog Man.



Billy and his family are watching TV when a news reporter announces that Petey has escaped and is vowing to get revenge. Just as the Hoskins begin to search for him, the doorbell is rung by P.T. Duckhat, "the world's most famous clown". He asks if Billy and Diaper Dog can participate in his parade; the Hoskins parents agree, and P.T. gets to take them to a big float of Super Diaper Baby. While everyone else is having fun in the parade, P.T. reveals himself as Petey. The parade float also turns out to be the Robo-Baby, who destroys the city with Billy and Diaper Dog in its powerful grip. Luckily, Dog Man scratches himself on its legs and soon, the fleas get in the Robo-Baby's diaper, making it leave, then they take Petey to jail. But on the way, Petey presses a button on his watch, making something appear, and he escapes, much to the surprise of Super Diaper Baby, Diaper Dog, and Dog Man.
