Reef Challenge is another one of the random background songs that plays in Challenge or Tournament games, not just in Challenge games as composer Rob Wallace intended. The song utilizes clarinet, celesta, trombone, bass, piano, and assorted percussion. Wallace began composing the song on March 26th, 1993 and the official title comes from the song's meta data. This is the longest song in the game, and, due to the short nature of the levels, would rarely be heard in its entirety.
