Anubis

The Anubis is a Mummified cobra-like creature that resides in the Spirit Temple in The Legend of Zelda: Ocarina of Time. These creatures move in sync with the player, but in the opposite direction. They will only attack when the player hit them with the sword, and then they attack with fire. They are also weak against it. Use the fire traps in the room with it or use a Fire Arrow or Din's Fire to decimate it, although the calm player could use it's mimicry to easily avoid it unscathed.
