There are several types of environmental puzzles that the player has to solve in order to progress through the game. Each one requires a specific head—the Bone head gives Fred sharp claws which allow him to climb on the sides of buildings, while the Shrunken head decreases his size dramatically and lets him navigate platforming levels, such as a saw mill. There is also a mannequin head that Fred must use to socialize with the residents of Hope Falls, because they are terrified of his other heads. There are nine available heads, seven of which are suitable for combat.
