Though the game's North American boxart is nearly identical to the original Rayman 2's Nintendo 64 boxart, the PAL boxart instead features Rayman holding a Yellow Lum and smiling to the camera. This boxart is also mirrored in the German release, most likely to prevent the rating label from obscuring Raymans face.

The spider-web in the Tomb of the Ancients located in front of the 1000th Lum doesn't have any bounce physics. This means that it is impossible to get the 1000th Lum without abusing a glitch in which the player must use an enemy's knock back effect to lift themselves up to it.
