Pony Gary Yellow is the sixth Chaos Beast in AdventureQuest Worlds.
Pony Gary Yellow is actually a small, plastic dinosaur carried around by Kimberly Freeman, the lead singer of One-Eyed Doll. Since Pony Gary Yellow was a dinosaur, Kimberly opened up a time portal leading to the time of the dinosaurs after the players fought and defeated many Music Pirates. There, Pony Gary Yellow was enlarged and brought to life. The players then fought against and defeated Pony Gary Yellow to Kimberly's dismay.
