Smiling Creepers. To tame them, you need to right click on the creeper with an apple in your inventory. It can also be eaten to restore all 10 of their hunger bars. Additionally, the Smiling Creeper Apple can be brewed with two bones and any kind of negetive potion to make it positive again. If cooked, the player will recieve a Burnt Creeper Apple, which poisons the player if they eat it.
