Tickbergers are fearsome hairy creatures. Quater warned that if you see one, you should run away. They seem to feed off of anything, but enjoy klay. In fact, they have the most annoying feature to always go after what someone wants most. When Hoborg was collecting klay, one chased after him (as Hoborg needed the Klay and the Tickberger thus wanted to have it too), Willie, and Bil. Besides this, they are very rarely seen.
