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.

Boounce is a care free balloon dragon, though she was had her close calls. As an egg Bounce was nearly at the end of her time to hatch and she was abandoned. She was taken in by Elenwen and was nursed back to health. She hatched and quickly grew into a strong, healthy, balloon dragon. Boounce will float high in the sky looking for other young hatchlings or eggs that are sick or near the end of their time. She will take them back to Elenwen and help them to hatch. Boounce will be friends with every one who is friendly and doesn't give a fig about anyone who isn't.
