Baikinman and Dokin-chan disrupt the yearly mushroom festival and carry off Kinoko, the girl Kamameshidon loves. A fairy of the lake gives Kamameshidon new strength, transforming him into Super Gold Kamameshidon. He sets out with the other members of the Donburiman-Trio to bring Kinoko back, but the group lands in Mushroom Valley and falls prey to the effects of hazardous mushrooms. Sushi-roll Maki-chan then appears to lend a hand. The film is the twelfth short movie in the Anpanman line, an adventure centered on the rescue.
