Tropic Island Hum, released in 2004, but originally recorded in 1987, is a song from Paul McCartney's second animated film for children.

It was subsequently released in 2004 on DVD by Miramax Films as one of the segments of Paul McCartney: Music & Animation.

[6] The film tells the story of Wirral the Squirrel, who was almost killed by soldiers.

Bison is the chief of that island, and Wirral's new love crush is Wilhelmina.

Then, all 3 of them (except Wilhelmina) get cleaned up and that night, they perform the theme song to the island.
