Dark green dragons, once they mature, appear to become an entirely different species. However, this isn’t true. Rather, they burrow underground and get nutrients from their vines. These vines are sometimes referred to as Dragon Grass. These dragons are very violent, and will use their vines to capture, kill, and eat anything that moves, as well as nearby plants. Luckily, their range is limited and they cannot use magic. Dark green dragons tend to be easy to spot since they usually kill all plants around them and thus are usually surrounded by a large clearing.

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.

Greeny Momo is a dragon that surely belongs to be in a dragon mental hospital. She always attacks everyone nearby, singing, "GREENY MOMO IS MY FRIEND." Since she can't stand five minutes without singing this and hurting other dragons, she has no friends. She also sometimes yells "YOGURT IS YUMZY IS MY FRIEND." which makes no sense at all, until you realize that she will attack anyone with yogurt until they give it to her. She then will eat the yogurt and will continue attacking the person or dragon.
