This beast is a nasty little bugger. I tried to combine as many elements of aquatic creatures as possible all in one.
Its stomach is filled with water in which many sea minions reside, which the King can spew out to attack anyone who dares approach him. His feet have lampreys' mouths on them to dig pits in the ground to fill with water and aquatic minions. It can also spray a jet of boiling water as well. In addition, with a flick of its tail, it can send its poisonous barbs flying, so watch out! It has sharp claws and teeth, and it has heavy armor on its neck. Finally, it has the ability to produce electrical attacks, particularly with its tail. And if you happen to get eaten, but avoid the crushing jaws, what ever is in his stomach will gladly finish you off.
