Yellow is a bird (confirmed by the game files) inspired monster who has a brown nest, a Helicopter-propeller, and two eyes with two long arms that seem to look like wings. He has sharp teeth, and has a pointed tail in his back. When he walks, he will keep his arms close together and stand tall, but when chasing after a player, Yellow will flap his wings with the mouth open (as shown in "Yellow Chase Cycle") and lean forward. In fans' minds, Yellow will mostly resemble as a Pterodactylus.
