Players move throughout a big castle, which is haunted with Boos. After a Captain passes a Boo Portrait, a Boo will come out of it. If a Captain is caught by a Boo, he or she will lose half of their Mini Stars. Boos will follow the players until they leave the current hallway, or enter an alternative room with lights. Before the players can face the boss, the Captain must roll a number higher than the specified numeral on the gate.
