Bone
Bones are an item primarily obtained by killing skeletons, strays, and wither skeletons, looting dungeon and bastion chests, or fishing as junk loot. They can also be crafted into bone meal, making them essential for farming and dye production.
Bones are mainly used to tame wolves, as feeding a wolf bones has a random chance to turn it into a loyal pet. They can also be used to breed and heal wolves, making them important for players who keep wolves as companions.
Additionally, bones are used in composters, and their ability to be crafted into bone meal makes them valuable for accelerating crop, tree, and plant growth. Due to their multiple uses in taming, farming, and crafting, bones are a highly useful item in Minecraft.
