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.

Green dragons are also sometimes called "earth" dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

Pebbledash, despite his cute-sounding name is possibly one of the loudest in the Never cave.

Although quite a lazy dragon, due to there being plenty of other dragons to care for him, he still likes to be active sometimes. Unlike one of his dragon sisters, Grafici, he detests the smaller dragons and hatchlings playing and sleeping on or anywhere near him.

Having said this, he cares a lot for the ever-growing family of dragons in the Never cave, and would defend them with his life.
