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.

Bright pink dragons are one of the few all-female breeds of dragons. Their bright colors make them easy to spot during dragon mating season. They are primarily herbivores, but eat meat during mating season when it is brought to them by a mate. Mating seasons occur once every 200 years and can last up to 2 years.

Lilyheart is the eldest of SunshineMew's dragons. She is very kind and often helps Lightbreeze take care of eggs and young hatchlings. Many dragons of the cave look up to her for wisdom and guidance, and she loves them all as if they were her children. She has many children of her own, including her oldest daughter, Diamondfrost.
