Balloon Dragons are so named because they are filled with a gas that makes them almost lighter than air, similar to balloons. However, they are not prone to bursting, as they are covered in tough skin and can deflate themselves if necessary. In addition, they generally are slow moving. They use their gas bladders to float to the tops of trees, where food is more abundant. They can shift their weight from their backs to their fronts, allowing them to reach leaves and fruit.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

When this dragon was just a wee baby, a red dragon broke into the nest where she was sleeping and attempted to eat her. However, her bouncy body proved impossible for him to bite through, to his great frustration, and before he could set her afire her parents returned and drove the brute off. While this experience traumatized her for life, a few individuals found it strangely amusing, especially after the aforementioned red said she'd had a sort of 'original gum flavor.' This led to her nickname, which has stuck with the poor creature ever since.
