One of the meanest dinosaurs. Usually looks older than it actually is. Can me identified with a very long, bird-like neck. Can be heard laughing, but sounds like squawking. Light in color and burns easily. While usually quiet, it's past time is "investigating," but is mostly just up to no good. *WARNING* DO NOT look it directly in the eyes.
