A short 5-minute story which was screened together with One Piece: Episode of Arabasta - Sabaku no Oujo to Kaizoku-tachi Dr. Mashirito and Abale-chan centers around Dr. Mashirito Jr. and his creation Abale, who serves as a rebellious opposite of the protagonist Arale Norimaki. About a year after the end of Dr. Slump, Dr. Mashirito Jr. returns to avenge his father Dr. Mashirito, the sworn enemy of Senbei Norimaki. He makes an android identical to Arale in every way, except for her personality. He gives the name "Abale" (meaning "rampage" or "brawl") to this android. In spite of Mashirito's evil intentions, Abale turns out merely to have a bad attitude, and she successfully contains the Tech-Tech aliens' invasion in Arale's absence.
