"These peaceful denizens of Rayman's world are the masters of magic and song. Inhabiting the many lands throughout the realm, each Teensie tribe has developed their own distinct musical style. Unfortunately, their melodious ways have attracted the Hoodlums, who have gone out of their way to imprison the diminutive minstrels. A reward lies in store for anyone who frees Teensies from their cages … got that, Rayman?"
For some reason I always forget about the "masters of magic and song" part, even though the doctors play music with Globox's body

Edit: I was wrong, that quote was included in the Cage article.
