Crystal is a squirrel modeled to look like a hooker. She is anorexic due to her heavy use of meth, wears a flowered dress, and has an air helmet on in order to breathe. A dead flower is also added as a decoration for her helmet.
Crystal, probably due to her heavy use of meth, is constantly jittery and psychotic. She is also shown to be a thief, as she stole Spliffward's wallet without him noticing.
- Crystal is a parody of Sandy Cheeks.
- She is one of the few characters to have her name in a title, while the first is Hashbrick.
