Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence 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. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.

Dragons don't communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.

Two headed dragons are a special breed of dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, attacking back and forth. They use their sharp teeth and wings to hunt large animals, and rarely eat plants. It is unknown what would happen if a two headed dragon were to mate with a one headed dragon, since it has never occurred. They only mate within their breed.

On the left, Kinkajou provides the never-say-die attitude, and will do anything to gain what she wants. On the right, Mozart just wants a quiet, happy life, maybe with some kids. Their desires conflict often, and it's usually Mozart who ends up unhappy with the end result. Still, they are joined for life. As time went on, they accepted each other more, and when they're not actively competing against each other, they are quite civil. A-chana seems to favor Mozart more, but she's quick to understand Kinkajou's drives, making it balance out. Despite that, whom one sister likes is different from the other. Gentle Mozart is close to Youssarian and Tina Sparkle. Tomboyish Kinkajou hangs out with Westbrooke and Swellow. It can be a pain sometimes.
