Grate Guy

Grate Guy is a jester and the partner of Knife Guy. The two work for Booster, not only as clowns but also as bodyguards. As Booster flees to Marrymore with Peach in tow, Mario is prevented from leaving Booster Tower by the pair of jesters. As such, Mario and company must battle Grate Guy and Knife Guy on the balcony of the tower. Grate Guy wields impressive magic, but he and his partner are eventually defeated.

Later in the game, Grate Guy opens up a casino. The entrance to the casino is well hidden in the underground of Bean Valley. Only those with a Bright Card, the casino membership card, may enter. Mario can win a membership from Knife Guy. The odds at the casino are terrible however; Mario and other casino members can lose a lot of coins here, much to Grate Guy's satisfaction.

Grate Guy holds no grudges against Mario and will even play the game "Look the Other Way" with the plumber. To play, Mario must guess which way Grate Guy will look, and look the other way. Essentially, the game has 50/50 odds. If Mario wins, he will be rewarded with sub-par prizes such as a Rotten Mush or a Wilted Shroom. However, if Mario plays a hundred times, he will be rewarded with the Star Egg, an extremely powerful item.

Grate Guy likes to balance on circus ball, just like Bowser's son, Lemmy Koopa.
