The Pachycephalosaurus is a legendary pet that was added in the Pet Mutations Update.

The Pachycephalosaurus sports a dusty rose-colored hide and carries its body in a forward-leaning stance, on the lookout. Its most notable feature is the bold red dome on its head, a built-in battering ram that makes it stand out.

Crafty Dome: Grants a 6% chance to duplicate a crafted item.
