I don't think they have any in-game description, and all we've got is their French name (Noirôdeur) from the old Rayman 3 website and the press pack, as well as the information that they basically spend their entire lives in holes, observing what happens outside.
While I don't know of an English version of the press pack, the old Rayman 3 website should have contained this information, and it may still be around.
Any idea what it's called?
