Grim is a Baryonyx of green complexion with red patches surrounding both eyes.
Grim appeared in Season 2 of Jurassic World: Camp Cretaceous. She first appeared in Episode 2 "The Art of Chill". Grim was a Baryonyx that was left alone in the veterinary treatment for unknown reason. She was left with other herbivores possibly for days or weeks until the campers found her. She was calling for her pack to free her as she called for her companions. Chaos came and tried to free Grim from her cage. She got her freedom when Darius freed her, and managed to help her pack against the Stegosaurus. She appears again chasing Brooklynn, Hap, and Kenji with Grim and Limbo. She eats Hap when he sacrifices himself to save the kids. Later, whereas the trio sleep, Grim awakes, hearing a noise. She finds Tiffany and charges her only to be killed. When Tiffany kills Grim, Chaos and Limbo grew furious, and avenged Grim by jumping on Tiff's boat and killing her.
- After one of the raptors from The Lost World: Jurassic Park and Charlie, Grim is the third named dinosaur to be killed by a human.
