Lemuzards are little animals used in one of the games of the Casino Gloum. The game consists of a lemuzard that is introduced in a square with four exit holes. Anyone can bet 1 zlito on one of the holes and if the lemuzard falls into that hole that person wins 10 zlitos.
Twinsen can use the Horn of the Blue Triton to cheat in the game, shooting hearts close to the hole in which he has placed his bet. This makes the lemuzard go in that direction, falling in the desired exit.
