Factual error: The alligator mentions wanting a Bananas Foster. This dessert was invented in 1951 but this movie takes place in 1926.
Other mistake: When the old woman is cooking gumbo in a large bathtub, it's shown boiling and really hot. Yet the two frogs can sit right on the rim of the bathtub inches above the boiling food in a non insulated tub without getting burned or even hot.
