Old Bitey is a giant Piranha that appears as the mini-boss on the Flooded Cavern levels in The Jungle. He is always found in the deep lake at the bottom of the level surrounded by a large shoal of ordinary Piranhas, and is very hard to defeat due to his high total of hit points and the fact that you need to fight him underwater, where your mobility is reduced. As with many bosses, killing Old Bitey unlocks a Deathmatch Arena.
