Aloha Hooey (1942)

Sammy Seagull and Cecil Crow have stowed away on the same ship. Cecil, from Iowa, wants to see a hula dancer; fortunately, they've just come within flying distance of a tropical island with a lovely dancer. They take turns trying to impress her, with such stunts as skywriting hearts (Cecil almost drowns) and fancy dives (Cecil almost crashes, then gets into a fight with a shark, a turtle, and a starfish).
