Ocean Jasper

The Snow Monster is a formerly corrupted Gem who first appeared in the episode "Gem Hunt". She was held captive by Jasper until "Earthlings", where she was forced into a fusion and fled after unfusing. She was later healed in "Change Your Mind".

Corrupted
While corrupted, the Snow Monster is a giant wolf-like creature with two horns. She has a mixture of turquoise-blue colors, with pink spots across her body.

Uncorrupted
Uncorrupted, this Gem has turquoise-blue skin and white hair, with pink markings on her body. She also retains the horns from her formerly corrupted form. She greatly resembles an Ocean Jasper.

"Gem Hunt"
She and Biggs are shown roaming the Great North and trying to evade Jasper. She is eventually found, poofed, and taken prisoner by Jasper alongside the other monster.

"Crack the Whip"
The Snow Monster and Biggs are used by Jasper in an attempt to attack the Crystal Gems.

"Earthlings"
In "Earthlings", she is shown imprisoned in the Beta Kindergarten alongside the rest of Jasper's Corrupted army. Jasper attempts to force a fusion with her to battle Smoky Quartz, but she breaks apart from the fusion and flees from Jasper.

"Change Your Mind"
In "Change Your Mind", she is healed by Steven and the Diamonds at Rose's Fountain, alongside other Corrupted Gems, healing just seconds after the Heaven Beetle and Earth Beetle are both cured of their corruption; breaking the surface of the Fountain right underneath the pair as Pearl smiles and hugs Garnet. She is later seen having a conversation with an unknown Gem with thick brown hair.

Fusions

 * When fused with Jasper, they form Zebra Jasper.
