Momotaro is a character from the Japanese folklore story Momotaro the Peach Boy. In Dr. Slump, he is a resident in Penguin Village. He initially lived in his story but when Arale used the Fairy Tale Machine to transport herself into the book, Arale messed up the story and accidentally brought Momotaro into the real world. Though an inconsistency, he has been shown around Penguin Village in several background and non speaking roles before Arale brought him out of the story.
