Big King houses in the shells of crustaceans. It lives in the ocean during childhood, and the adult Big King will leave the ocean to migrate to the distant land. But they come back time to time to choose another shell, which is more suitable. The Big King has great strength. It can jump to a certain height and heavily hit the ground to make the earth shaking, while the general weapons almost can't hurt it for the protection of the shell. The weakest part is its legs. When the Big King is foaming at mouth, that doesn't mean it's dying, but an expression of anger. You have to be very careful at that moment.
