"The Femur of Fury. Useful for mangling mosquitos."
The Bone Crusher is the sword-type weapon of Prehistoria. It is the first weapon the player acquires, not counting the bazooka in the intro of the game. The hero finds it when his dog retrieves it for him in place of a thrown stick. It is known as "the femur of fury."
Despite being classified as a sword, the Bone Crusher has no cutting ability; it cannot cut down the plants that bar the player's path in early areas. The player needs the Spider's Claw or Horn Spear for this.
The Bone Crusher's level 2 attack is to swing it overhead in front of the hero. It's level 3 attack swings it overhead twice while charging forward.
