Betty and Bimbo take a trip to Crazy Town for a small vacation where anything can happen. They arrive on a train that acts like a horse. Mice are roaring and birds swim in the lake while fish fly in the air. Hats are worn on feet and shoes on heads, while banana peels are eaten instead of the banana.
Fish lure humans into the lake with bait, while women replace their own heads with mannequin heads, as well as cats in a zoo barking with hippos meowing. Betty and Bimbo perform "Let's Go Crazy" for all the animals in Crazytown on a piano which appears out of nowhere from the ground, and after the performance (where, at one point, Bimbo plays the piano with his rear end), the two kiss.
