The Worm Monster is a corrupted Gem that first appeared in "Bubble Buddies".


As her name suggests, the corrupted Gem takes on the form of a giant worm-like monster. She is relatively long, and the width of her body is nearly equal throughout her entire length with her head enlarged into a spherical shape, where a circular mouth is located at the end. The body is colored light brown with scattered spots in different hues of purple and blue across it. Her entire body is covered in a thick, shiny translucent light blue coating that includes three tentacles near the mouth. The mouth is circular with multiple rows of white teeth present, each tooth in a circular arrangement in each row. She has a red gem located inside her mouth that gives off a red glow that passes through the skin and coating, creating the illusion of eyes on the head.


Bubble Buddies

The Worm Monster is first seen at the bottom of the ocean, eating glowing seaweed. She possesses a habit of burrowing into the ocean floor, resulting in frequent tremors and loud screeching to erupt throughout Beach City.

After falling to the bottom of the ocean, Steven and Connie see the Worm Monster for the first time. The creature then dives into the ocean floor, causing the ground to shake and crack open, making Steven and Connie fall into a pit. The monster reappears after Connie and Steven reach the surface of the ocean and chases them to the shore. Steven notices the creature is attracted to Connie's bracelet because it glows. Grabbing it, he leads the monster around the pier supports, causing them to break and crush the Worm Monster beneath the pier, she then explodes and Garnet bubbles her gemstone.

Ocean Gem

She is seen in the flashback as Pearl explained about the corrupted Gems.

Catch and Release

Her gemstone can be seen in the Burning Room, still in her bubble.

    • Subterranean "Swimming": Her ability to swim is not limited in a liquid medium, she can also burrow and can move at high speeds underground.
  • Enhanced Roar: She has roars so loud that they can cause disturbances on land ranging from mild tremors to being able to break off parts of structures.
  • Enhanced Resistance: The Worm Monster's body also has great tensile strength as she can stretch around the pillars of a pier multiple times, before reaching her limit.
  • Red Light Perception: Although the monster has no eyes, she can detect red light allowing her to find her favorite food, fluorescent red seaweed, as well as Connie's scarlet glow bracelet without bumping into anything while on land.
