My Green Fedora is a 1935 Warner Bros. Merrie Melodies animated short film directed by Friz Freleng.
Peter Rabbit is assigned by his mother to babysit his baby brother Elmer.
When Peter is not looking, a weasel snatches the baby and runs off to the tunnels underneath the house.
Peter gives chase and manages to take care of both the weasel and Elmer with a garden hose.
The Motion Picture Herald gave it a below-average review due to the perceived scariness of the weasel, calling it "Not quite so good as some of this series.
