Crayon Shin-chan: Explosion! The Hot Spring's Feel Good Final Battle

A crash-landed alien robot buries itself deep beneath a famous hot spring resort. Its mission: drain the Earth's precious "Earth Energy" to save its own dying world. The only one who notices the strange changes befalling his hometown is a mischievous five-year-old, Shinnosuke "Shin-chan" Nohara. Armed with crayon drawings and chaotic charm, he must rally his family and the entire Kasukabe Defense Force against an otherworldly threat. This 1999 animated action-comedy turns a planetary crisis into a playground battle, where saving the world depends on a kid's crayons and a really, really good bath.
