Crayon Shin-chan Movie 15: Invoke a Storm! The Singing Buttocks Bomb

あらすじ

A slapstick comedy on a bomb uproar, and a touching story about the ties between the Nohara Family and their dog Shiro. A film in the musical style including the scenes with inserted songs. When the Nohara Family enjoy a trip to Okinawa, a strange object like a flying saucer becomes stuck with Shiro's bottom. That is a special bomb dropped by "The Only Buttocks Aliens," and it has the power to destroy the whole earth. The space monitoring center "UNTI" begins to pick up the bomb, but a female terrorist group "Hinageshi Opera Company" tries to get the bomb and disturbs UNTI's work.
