Pretty cool looking and can be tamed! Keep an eye out for them in swamps! These critters give you extra health points when you need them. Yes they do. Watch your health bar next time you've got one of these as a pet and you get hurt! Extremely useful when battling mobs. Better than a potion of regeneration... They love water, and restore their health quickly when in or near it.

How to Kill
But why? Why would you do such a thing?
Raw fish to tame. Dead bush to un-tame. Ruffles on the head indicate health. Tail wagging indicates sitting or not.
Use a Crystal Apple from the Termite Crystal Dimension to put your pets "in the mood". Babies will automatically never despawn. No zookeeper item needed!
