Trivia

 * This is a decent pet for grinding Zealots, because the player doesn't have to stop and empty the inventory, or craft enchanted ender pearls every few minutes. However, with a sack or personal compacter, you no longer have to do this making the Endermite Pet less useful. Thus, an Enderman Pet can be used with a combat sack.
 * However, the Endermite Pet still provides for consuming ender pearls.
