A Box Boy is a rare, haunted chest that can be found in Bean Valley in Super Mario RPG: Legend of the Seven Stars. Box Boys resemble pudgy ghosts hiding in Treasure Chests. When the chest is closed, Box Boy looks like a regular Treasure Box; this mimicry allows it to easily prey on adventurers searching for valuable items, such as Mario and his party. It can also be encountered if the player has fought it already and every symbol in a "roulette" treasure box is different. In battle, Box Boy is a tough opponent: he has high attack, high defense and high HP. It is also unaffected by status ailment-inducing attacks. The best way to defeat Box Boy is to make good use of its weakness to Jump.
Box Boy uses a few special attacks, including Scream, a technique that cuts a party member's attack and defense in half, and Carni-Kiss, a powerful bite that causes significant damage. Moreover, Box Boy often summons Fautso, another powerful enemy. Fortunately, Mario and his party get 150 coins and 100 Experience Points for defeating Box Boy. Chester, Hidon, and Pandorite are enemies similar to Box Boy.
Coincidentally, the ghost within the Box Boy bears a heavy resemblance to Peepa.
