Tinsuit

Tinsuit is a monster appearing only in Zelda II: The Adventure of Link. It occurs only in the palaces, where it charges mindlessly in one direction. It will change direction on running into a wall, but will walk straight into pits. Certain corridors have infinitely respawning Tinsuits.

Tinsuits have wolflike heads as depicted in official art. Their in-game sprites carry swords, but do not use them. Even early in the game they don't do much damage to Link, but they can deduct experience points if they hit him.
