The official Dragon Ball website’s thirty-sixth entry in “The Nearly Complete Works of Akira Toriyama” — an on-going series highlighting rare and important pieces of the author’s work over the years — is a citation for and the title page from the 2007 Dr. Slump special chapter “Dr. Mashirito — Abale-chan“.

The special chapter was published 06 March 2007 in the April 2007 issue of (the now-defunct) Monthly Shōnen Jump. In the story, the son of Dr. Mashirito (the fictional evil scientist version of Toriyama’s original editor Kazuhiko Torishima) builds an evil version of Arale named “Abale”. A five-minute animated adaptation was created and ran alongside the eighth theatrical One Piece film (“Episode of Alabasta”) just a few days prior beginning 03 March 2007. Toriyama’s author comment alongside the chapter in Monthly Shōnen Jump may be referring to its adaptation into an animated feature:

The title page artwork was recently included in the 2013 Dragon Ball Chōgashū: Super Art Collection.
