In Adventure, the player's goal is to recover the Enchanted Chalice, which an evil magician has stolen and hidden in the kingdom, and return it to the Golden Castle.[1] The kingdom is made of a total of 30 rooms, with various obstacles, enemies, and mazes located in and around the Golden, White, and Black Castles. The kingdom is guarded by three dragons—the yellow Yorgle, the green Grundle, and the red Rhindle—that protect or flee from various items and attack the player's avatar.[2] A hostile bat can roam the kingdom freely, carrying an item or a dragon around; the bat was to be named "Knubberrub" but the name is not in the manual.[3][4] The bat's two states are agitation and non-agitation. When in the agitated state, the bat will either pick up or swap what it currently carries with an object in the present room, eventually returning to the non-agitated state where it will not pick up an object. The bat continues to fly around, swapping objects, even offscreen.[5][6]
