This is Paboo, the protagonist of Paboo and Mojies. In one episode, during a thought sequence of his, he hatched out of an egg wearing this red sleeper. Sadly, we never know if he was wearing a diaper under it, until now. One Day, Paboo found a new magic word in the Mojies book, baby. This regressed him to a baby and shrunk him out of his clothes. His friends had to diaper and put a sleeper on him. Then while trying to figure out a way to change him back, his sleeper flap popped off and he just smiled at them. You may think I didn't have anything to do with this incident, but I was the one who put that word in the book, so I did.
