Bumpy is an adolescent ankylosaurus. At 7 feet tall, she is a bit shorter than an adult of her species.

Bumpy's name is a reference to the asymmetrical bumps on her head.

Her favorite snack is the berries that grow on Isla Nublar.

She grew from a hatchling in just a few months due to her accelerated growth rate.

Bumpy is a friend to humans and especially devoted to Ben Pincus, having imprinted on the boy moments after hatching.
