Unlike [[Rayman 1|the original game]], the player can advance to the final boss level without freeing all 80 cages. The cages in this game are a lot smaller this time, and are mostly hung from ceilings and posts, containing several kinds of creatures and spirits such as [[Teensie]]s, [[Familiar Spirit]]s (''[[Rayman Revolution]]'' only), [[Deny]]s, [[Ludiv]]s (PlayStation version only), and both [[Yellow Lum|Yellow]] and [[Purple Lum|Purple Lums]]. Also unlike [[Rayman 1|''Rayman'']], they do not appear by touching certain areas in a map, though some are hidden and can only be reached after [[Rayman]] receives certain powers, so the player would still have to backtrack. [[Rayman]] would know that one is near by hearing the sound of a prisoner crying for help. For every ten that he destroys, his life bar increases, though in ''[[Rayman Revolution]]'', it indicates that [[Rayman]] has enough Familiar Spirits to unlock another of [[Ly the Fairy|Ly]]'s minigames (which, when completed, will increase [[Rayman]]'s maximum health).
