She was living in a hidden bunker in the corn maze created by Peridot and Lapis where she hid with some raccoons until she was disturbed by Lars, whom she tried to attack but was poofed by Garnet and bubbled.
The monster lizard Gem was later released back to the bunker after the entrance was covered with a rock.
The Monster Lizard Gem appears as a huge, light-green, aquatic, reptile-looking creature with yellow spots. She has fins on the sides and back of her head, chin and front legs. Her faceted lime gemstone is located inside her body.
