In the short film 'Momotaros's Summer Vacation,' situated between the Gekiranger movie and 'I'm Born!,' a unique blend of live-action photos, 3D computer graphics, and traditional animation creates a captivating 'Momotion Picture.' The story unfolds with Momotaros proudly showcasing his strength, only to be challenged by Sha-Fu to prove his prowess in swimming. Amid teasing from Urataros and Ryutaros, and a scolding from Kintaros, Momotaros finds encouragement from Deneb to believe in his swimming abilities. However, as the fleeting confidence wanes, the Imagin and Sha-Fu remind the audience of the impending movie debut.
