The Grey Wollywog is a variant form of the Wollywog. It is silver colored, while the lower half of its body is bronze. Its legs are also bronze with silver toes, red eyes, and it's shaped like a Yellow Wollywog. It attacks like a normal Wollywog, but when it hits the ground, it unleashes a gray shockwave outward 360° at your Pikmin, knocking them away. The shockwave fades quickly, so get out of the way and you should avoid it.
