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.

Bubbling Happy Balloon was brought to the cave by a caretaker. Except, he wasn't brought as an egg. The dragons in this caves' caretaker brought him as a hatchling, for no one seemed to want him. He loved to play and mess around, always letting himself float up for the amusement of others. When he matured, he still kept his happy attitude, sometimes even going far enough to play little pranks now and again. But what really brought him slamming down into reality was Krystal Klear. The white dragon had gotten through to this... unique dragon. It took a while for them to actually decide what they were going to do; Whether to be mates or not. But now, they are mates, two dragons that really love one another.
