Cool mob idea: The Kraken (from a long ago mob vote)

The Kraken does have an available spawn egg, but can also be summoned in survival. How to summon: place 4 candles in every corner of a square made out of the block of your choice. Next, light the candles. After that, place a full stack of slime balls in the middle of the square. All of these steps should be taken in the ocean for summoning. Congratulations! You have summoned The Kraken. Now, for stats. It's a boss, no dip cuz it's the Kraken, it's health is about the same as the withers. NOW for the design. This can be however you like.
