Bananamental

The Bananamental can make stomp attacks with each part of it's body.
Each individual limb, of which there are 4, as well as it's head has 50 hit points. And each takes damage individually. Saving throws are made as one but only the body parts within the area of effect lose health. The hit points displayed above are it's main body's.

With every attack the Bananamental makes it takes half the damage it deals (regardless of wether or not it hits a creature) to the limb or body part it made the attack with. Until eventually it's just a large banana that's squirming all over the place.
