Diaper Dog

Diaper Dog (formerly as Danger Dog) is Super Diaper Baby's sidekick. He defeated Deputy Doo-Doo and Rip Van Tinkle with him.

He is Super Diaper Baby's best friend and pet who shares the same powers as him. His heroic, helpful, clever and obedient personality is a big help to him and Billy Hoskins when they're fighting crime and the forces of evil.

The Adventures of Super Diaper Baby
Diaper Dog was originally Deputy Dangerous' sidekick and partner, Danger Dog. One day, the evil cowboy attempted to kill his nemesis, Billy Hoskins (Super Diaper Baby). Diaper Dog rescues his new pal and they return home, where the landlord makes the new hero wear a diaper for the time being so he doesn't "go pee-pee on the carpet."
