Notice a (possible) nod by Tim Burton to the 'chimp siren' shown here in Nightmare Before Christmas (1993).
Among the wild beasts shown is a moose, which normally doesn't live in a jungle. That's Hollywood!
The bananas Popeye tells the gorilla to sell are shown as costing 3¢ a bunch.
A popular sight gag of Popeye transforming a predator with a punch is used here, as well as big fish into tiny sardines and animals into fur garments. Other uses in future shorts would be bulls into meat cuts and alligators into luggage.
