The "Friendship Song" is sung by Boober and Red while they are trapped in a cave-in in the Fraggle Rock episode "Marooned." The song gives them the motivation they need to keep up hope that they will be rescued. A reprise of the song occurs at the end of the episode, with slightly different lyrics to reflect the happiness of the Fraggles after Boober and Red are saved and Boober's birthday party can begin.
