Toppo

The Rabbit Fang is a small corrupted creature that is found in some of the more peaceful places in the Dark World and Light World. These little monsters can be defeated by means of your sword and any other weapon you choose. Additionally, removing a patch of grass they are about to jump out of or land in will cause the Rabbit Fang to lie on the ground helpless. If you touch the helpless rabbit fang it will say "Take it, thief" and disappear in the typical skull puff of smoke leaving the item you would have received for slaying it.
