Chunkyceratops is a hybrid creature confirmed to appear in Additional Creatures. It is noted to be primarily a hybrid of the Chungkingosaurus and Eotriceratops, having characteristics of both like venom and the ability to charge and jump. It is meant to be the perfect combination of offense and defense. While its appearance and characteristics are known, its role ingame is not. It's not known if its even a boss or has characteristics akin to other hybrids, albeit it is speculatively thought to be so right now.
