Urusei Yatsura: The Shougaibutsu Suieitaikai

A scorching summer day has the students of Tomobiki High dreaming of one thing: finally getting into the school pool. The principal and Onsen-Mark have other ideas, transforming the route to the water into an outrageous obstacle race and dangling freedom from summer homework as the reward.

What follows is less a sporting event than a school-wide disaster. Traps, rivalries, bizarre creatures, and Lum's alien powers pile one problem onto another until simply reaching the finish becomes nearly impossible, and the promised prize proves almost as troublesome as the course itself.
