Piranha

Piranhas have 30 health and can be found in water in the Jungle, Underground, Cavern layer, and potentially the Underworld if it is flooded with water. They swim in a straight line left or right until hitting a wall, where they flip directions. They will swim towards the player if he/she is submerged in water; otherwise they pay no attention to the player.
