What type of animal she is is currently unknown, though she does have some feline features. She is a purple creature with long flowing hair. She has a black nose which is accompanied by some whiskers. Since Episode 155, her eyes have been all-over red.

Her Plan
Her plan against Mylo has three phases

Phase 1

 * Phase 1 was most likely Kidnapping Mylo's Papa.

Phase 2

 * Phase 2 of this plan was Barkley using Mylo's Mask and Clothes Attacking Mylo's fans ruining his reputation. Barkley used Skateboard to Traverse the city looking for Mylo's fans. Mylo's Fans were to only be attacked once
 * It's worth Noting that Barkley poorly handled it's job as he attacked Garrison Gator twice which was not the plan, also 2 People noticed that Barkley wasn't Mylo, those people were:
 * Calum Bullock
 * Casey Chipmunk

Phase 3

 * When Rylo asked her what Phase 3 was she replied "If Papa won't speak, we make him speak" implying that Phase 3 (or part of it) is forcing Papa to speak about Mylo's Powers

Trivia

 * She wears the same clothes as Lulu the Cat
