Momotaros no Natsuyasumi is a short film released between the Gekiranger movie and I'm Born!. It blends live‑action photographs, 3D computer graphics, and traditional animation, collectively referred to as a Momotion Picture. The story follows Momotaros as he gloating about his strength until Sha‑Fu challenges him to prove it by swimming. After being mocked by Urataros and Ryutaros and confronted by Kintaros, Momotaros is convinced by Deneb that he can swim. When the “mind over matter” influence wears off, the Imagin and Sha‑Fu announce that the movie will be coming up soon.
