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.

Floatyzine is a Balloon dragon, something obvious by his appearance. While trying to capture his egg, his owner and her dragons found themselves running around the Dragon Cave trying to catch the frustrating deep pink egg that persisted in floating just out of their reach (and avoiding other egg snatchers at the same time). The egg was finally caught when Rose Satin the Red cracked and threatened to scramble it with a jet of fire. It promptly floated into his owner's arms. As a hatchling, Floatyzine behaved like his egg, bouncing and floating out of Losara the Guardian (and babysitter's) reach and randomly bumping people on the head. But the hatchling also found himself crashing against the ceiling and cave walls, and in one extreme case even floting into outer space! This was remedied by tying his foot to a long rope until he learned how to control his movements. Now this goofy dragon is well liked by everyone in the cave.
