An April Fools' Day prank between Gegege no Kitarou (2018) and Fuji TV. It shows Medama Oyaji playing around with the Fuji TV mascot, since both the anime and these prank shorts aired on that TV channel. Toei Animation posted a compilation of all 3 shorts on their official YouTube channel.
Three 10-minute videos present a trippy view into the minds of their creators. Brought together by Pierre Taki of Denki Groove, Mechano: Scientific Attack Force features three shorts done in very different styles.
The three short films are:
"Plastic Gun Man" - a 3D Western spoof
"World Meccano Triangle" - a music video reminiscent of '90s era screensavers
"Haiirogaoka no Soridaijin" (translated as "Prime Minister of Gray Hill") - an anime-style animated video parody of Akira Mochizuki's famous 1977 manga, Yuuhi ga Oka no Souri Daijin
