 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 <unk> 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 .
