Animals' bones are items used in the Mage Training Arena Graveyard chamber. Players must cast bones to bananas or bones to peaches on the bones after removing them from various piles within the arena. The fruit can then be eaten to recover life points or deposited for pizazz points.
The Mage Training Arena interface shows numbers near each of the bones. This indicates how much fruit will be obtained when the player casts bones to bananas or bones to peaches. The values will intermittently change.
