Tropic Island Hum, released in 2004, but originally recorded in 1995, is a song from Paul McCartney's second animated film for children. The associated single reached #21 in the UK.

The "Tropic Island Hum" film is from a story and screenplay by Paul McCartney, who with his wife, Linda McCartney, provide all the character's voices. They were also the Executive Producers.

The film was first released in cinemas as the short in support of Disney's Hercules movie in 1997. It was subsequently released in 2004 on DVD by Miramax Films as one of the segments of Paul McCartney: Music & Animation. The DVD also includes Rupert & the Frog Song, and Tuesday.

The film tells the story of Wirral the Squirrel, who was almost killed by soldiers. Froggo helped him and took him to another place he would go. He couldn't go back there again! But then, he finds a tropical island. 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. Bison sings the first part of the song. A parrot gets banged on the bass drum and is dizzy. Later, an alligator sings. Right after that, Wirral blushes at his new love crush Wilhelmina. Then a bad thing appears, the mask-animals try to ruin the party, but then, a school appears, and at the end Wirral & Wilhelmina kiss.

All songs written by Paul McCartney.
