He was a boss in A Link to the Past and in the original Link’s Awakening as well. He serves as the first boss in this remake too.
He looks like a caterpillar and a hamburger fused together.
He’s not too hard to defeat, you just have to attack his tail enough times.
And he’s done long before the edge of the floor is totally crumbled. A simple but decent battle.
For which you get a Heart Container and the Full Moon Cello when you’re done.
