Adventure Time Ending Theme

The "" is a portion of the song "Christmas Island" or “Island Song” by Ashley Eriksson with slightly altered lyrics. A version of the song also appears on the LP Let's Build A Roof by LAKE, a WA-based band, of which Eriksson is a member. The end credits sequence does not include the main characters, but instead shows a Bee, a Worm, and various insects on a grassy field. The full credits are not usually seen on Cartoon Network airings, but appear on full online episodes and On Demand. You can listen to it on Adventure Time Official's Soundcloud : https://soundcloud.com/nina-brady-1/island-song
