A tiny frog and his kid arrive on an island and turn the whole place upside down, and that's the entire plot. What matters is how the film finds comedy in pure character friction, watching two forces of nature collide with a world that has no idea what hit it. The animation moves with a looseness you don't see in later work, giving every frustrated islander and stubborn amphibian genuine personality. This is a film that knows a good joke doesn't need explaining. It just needs a frog being relentlessly, unapologetically itself.

A fierce, hot-tempered frog and his son turn up on a tranquil island, and wherever the pair go, trouble follows. Their arrival throws the lives of the island's inhabitants into disorder as the two newcomers leave chaos behind them. This fantasy film is a Japanese animated feature from 1959, remembered as one of the notable Asian animated movies of the late 1950s.
