Season 1931

Bimbo prepares to rob a train that he has forced to stop. He then sings "The Holdup Rag." A ferocious bearded cowboy emerges, eats the barrel of Bimbo's gun, and, pulling off his beard and costume, reveals himself to in fact be his wife Dangerous Nan McGrew, whom he had abandoned. She then throws Bimbo into the locomotive, disconnects it from the rest of the train, and they drive off.

A Bouncing-Ball rendition of the title song features animated cats.

In a vaudeville act, Betty Boop (with dog's ears) sings "You're Drivin' Me Crazy;" Bimbo sneaks into the show and runs afoul of a stage hypnotist.

The surreal, nightmarish atmosphere of Bimbo's Initiation has made it one of the most renowned Fleischer Studios shorts.

So the king and bimbo fight with wooden swords. Bimbo loses and is taken away by a knight, but Bimbo soon realizes it is Betty and asks him to marry her.
