Seasonal Dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

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.

Leafy Green Happiness is always very happy.  She likes to bounce around with Petite Pufftyball and skim the water with Teal Tree Frog.  Battle-training alongside Cry of the Crow and soaring high in the clouds during thunderstorms with Thunder of the Mareep, she is a very friendly dragon.  She also plays with He who Dwells in the Rainforest and The Whipping Boy on a tropical island, roosting in trees and looking for stuff to eat.  She also is very agreeable and swift.  As a Seasonal Dragon, she wants to see other species of her breed, like the Winter, Autumn, and Summer equivalents of her.  She is looking forward to Summer, as she probably will get a Summer Dragon friend. Her plan is that in the Winter and Fall, they can breed and lay a Winter and Fall Seasonal, so then she will not be the only Seasonal Dragon on Tailspinner's scroll.  Tailspinner likes that idea too, as then she will have more dragons.
