Bats are a type of hostile mobs which spawn in caves and dungeons. Bats usually spawn as group of 2 or more bats, but they can also spawn individually.
Bats will fly directly at the player and use their fangs to bite the player. When they start running low on HP they tend to fly into the air to avoid or disorient the player and continue the attack from behind. Be careful, if encountering a group of bats because they can easily swarm a low level player.
Bats can be tamed with Mango Juice and drop a range of food types.
