Aquatic Copper Golem Variant

Due to the change where drowned drop copper ingots we should now have an updated "Aquatic Copper Golem." This would take the form of a mermaid or shark and a player could create one by making a shape 5 copper blocks long and then placing a carved pumpkin at the end. A copper golem would age from bronze to the weathered variant similar to normal copper blocks. These would be useful for raiding drowned ruins or defending against guardians. A copper golems attack would include biting or thrashing around as opposed to the arm attack of a normal iron golem.
