Rumpus is a bright purple Thunderclaw with a pale pink underbelly. She is often seen with her tongue out as it helps her track.
- Sense of Smell: As a Tracker Class dragon she is great in tracking and searching for objects, using her tongue as a guide to do so. However, she uses this skill to find pie to eat.
