A 1942 propaganda film that throws monkeys in fighter planes at polar bears and commits completely to the bit. Nobody remembers this exists, which means you get to watch wartime absurdism before anyone else does. The combat is real animation work, not a five-minute joke. This is the moment anime stopped being cute and started being feral.

Monkeys go to war against polar bears in this short film from 1942, and the fighting takes place in the air. The two sides clash in aerial combat across a single episode. The original title identifies the monkey Sankichi and frames the story as an air defense battle.
