Crayon Shin-chan Movie 15: Arashi wo Yobu Utau Ketsu dake Bakudan!

During a family trip to Okinawa, Shinnosuke's dog Shiro accidentally becomes the carrier of a bizarre alien bomb attached to his backside. The device cannot simply be removed, and its destructive power is enough to threaten the entire planet. A space-monitoring organization moves to secure Shiro before the worst can happen, while another group wants the bomb for its own purposes.

To the authorities, sacrificing one dog may seem like the simplest way to save Earth. To Shinnosuke, Shiro is family. Refusing to hand him over, the Noharas flee with their beloved pet and become the center of an increasingly ridiculous pursuit, turning a planetary emergency into a desperate test of how far a family will go to protect one of its own.
