The manager of a casino ship inspired by a ghost ship. Grappa looks like a piggy bank, but he's actually a monster that feeds on human desires. In fact, the casino he controls is a casino where "gold coins rule the customers", and the coins used in the casino have their own intentions. At the end, when Jing took away his desire, his true body, which looked like a combination of a huge gold coin and an insect, was exposed and he died after receiving a Kir Royale. Grappa appears as a boss in the Game Boy Color games.
