Shy Guy

Mask-Mimics are easy to defeat creatures found in Link's Awakening. They copy all of Link's movements, but go in the opposite direction, (for example, if Link moves to the right, they go left) and cannot be hurt from the front due to their masks. The easiest way to defeat them is to trick them into exposing their back, and do a Spin Attack.

Trivia

 * Link's Awakening was full of Mario cameos/references, and the Mask-Mimic is just another one of them, as they resemble Shy Guys from Super Mario Brothers 2.
