An Imagin short shown between Juken Sentai Gekiranger: Nei-Nei! Hou-Hou! Hong Kong Decisive Battle and Kamen Rider Den-O: I'm Born!. Momotaros gloats of his strength until Master Sha-Fu dares him to prove it by swimming. After being made fun of by Urataros and Ryutaros, and bashed by Kintaros, Momotaros is talked into believing he can swim by Deneb.

The Taros get into another crazy adventure as they take the Ginjiro out for a spin.

Originally shown in theaters after Kamen Rider Kiva: King of the Castle in the Demon World and Engine Sentai Go-onger: Boom Boom! Bang Bang! GekijōBang!!, with Ryutaros found by Momotaros as reenactments of the two movies by the Taros are played on the movie screen.

An animated short shown with Farewell Kamen Rider Den-O: Final Countdown. In the short, Momotaros feels bad that it is really the end of Kamen Rider Den-O as Urataros assures him that all good stories have to end sometime. After Kintaros and Ryutaros try to make sequels to classic stories that cannot have a sequel, the Imagin end up on the moon in homage to Galaxy Express 999, embracing their final story. A later retelling of this short, Be Forever Momotaros: Imagin Terminal Station, provides an alternate ending where the story does continue with numerous new characters and Momotaros freaks out about it.
