The Rayman is one of the tougher secondary secret weapons to get because of the Dahaka. It is located in the Catacombs. (Where you have to pull those three stones out of the wall to raise the central area.) After pulling the first, go to the stairway, make a right, run on two walls and jump to the bar on the right side. Swing from the bar and follow the path. (Make a quick left.) Then use the Scorpion Sword to break through and retrieve the Rayman Fist. The Rayman fist is unbreakable and has a high attack rate but does little damage. If you throw it, you lose it for good.
