Exit signs are signs that Rayman must reach to end a level's part, to then continue onto the next part or the end of the current level.
Another exit sign has an arrow on the front of it, treats another purpose, so if Rayman touched it, it wold send him back to the world map. These are seen at the beginning of each level.
Exit signs only appear in Rayman and its remakes.
Exit signs are chestnut brown in colour and have an exclamation mark in the middle of it. The other exit signs are the same except that they have an arrow pointing left.
