Bone

Bones are items dropped by skeletons and Wither Skeletons upon death. They can also be found in chests hidden in Desert Temples and Jungle Temples.

Uses
Using a bone on a wild Wolf has a 33% chance of taming it. Bones cannot pacify an angry wolf.

Bones can be used to make Bone Meal, which serves two main purposes:
 * As a fertilizer, which grows many plants to their fully mature state after 2-5 uses.
 * As a crafting ingredient in Wool Dyes.

Trivia

 * As with Sticks, Bones are wielded as a tool instead of an item.
 * The bone appears to be the femur, the humerus, or the tibia of a human.
