Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
The last thing I expect to see in a Busby Berkeley musical is a frog, or any animal for that matter. There's hardly time for anything more than a few comic characters and a thousand young white chorus girls dancing in unison on moving stages, and there are plenty of them here. This one won an Oscar for it's "Lullaby of Broadway" number.
In the beginning we are introduced to one of the movie's eccentric characters (Hugh Herbert often played lovable wackos) by showing him walk past a fountain in the middle of the lobby of a fancy resort hotel and hearing a frog croaking. (It's a bullfrog that makes the sound of a Pacific Treefrog.) He pokes it with his cane and calls it a bad boy. Maybe because the frog isn't supposed to be indoors. Maybe because it was funny in 1935. Who cares, bring on the dancing girls.
