In J&D's ToonWorld, Cassie is a good friend of Luna the Dragon. Cassie is also close friends with Pinch Raccoon, Sunny Funny and Nutsy Koala.
Cassie is a dragoness with pink scales and a few yellow scales starting from the top of her head that turn orange as they reach her back. She has blue eyes and small horns on the side of her head, along with a few light blue speckles on her arm, thigh and tail area. She has brown spikes running down her back, sharp claws on her hands and feet, and she has two fangs showing, while the rest of her teeth are human-like. Her short height makes her the smallest among her dragon friends, but is still bigger than her human friends as she is still slightly taller than Enrique. Her dragon badge is that of a light blue orb hung around her neck by what appears to be a gold necklace.
Out of everyone in the Dragon Tales main cast and despite her cuteness and beauty, she is shy most of the time, but makes up for it with her extensive knowledge of Dragon Land.
- She is probably J&D's favorite Dragon Tales character.
