Knot Deer is a skinwalker from the animated series: Crossing Worlds.
In the episode: Double Trouble, he is spawned into Felix and Jake’s home when Jake’s powers spaz out and summons a portal spawning Knot. Knot offers to take Jake’s place and do his chores while the real one goes and explores a supernatural academy. However, Knot Deer secretly wants to go and eat Felix and later Jake as a meal! Luckily, he is outmatched by Felix and tossed out a window. Knot can shape his body into anything.
