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.

The mate of PizzaG, PieWv is a perky enough dragon. They originally were paired up by Mut-Amore but have stayed together, one of the rare cases where mutamore "shipping" actually works. She is a bit fruity and very sweet, which Pizza found strangely adorable, and he certainly doesn't mind her tendency to gush all over things. She has a funny metal bed she sleeps in so she doesn't float away, which she calls her 'tin'.
