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.

Dr. Slump creates a little android girl, Arale, who is very stong, happy, and totally common senseless. They live in Penguin Village where the strangest things happen (e.g., the dawn is announced by a little pig wearing a basquee).

She retired in May 1985 when her health suddenly became worse and was subsequently replaced by other people for her roles.

Basking in the glow of his scientific achievement, Senbei scrambles to get Arale in working order so the rest of Penguin Village won't have reason to suspect she's not really a girl. But first Senbei needs to find her a pair of glasses and some clothes...

Professor Senbe Norimaki, aka Doctor Slump, is a bumbling inventor living with his wife and his out-of-control robot daughter, Arale. The trio frequently get involved in surreal adventures with the other inhabitants of their strange land, which include sentient trees and mountains, a not-so-super superman, and alien invaders that just want to go home.
