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.

I'm Busy Doing The Fishstick is probably the craziest dragon in the entire Cave. Every time someone disturbs him, he always says "Can't you see! I'm busy doing the fishstick—it's a VERY delicate state of mind." What a fishstick is, nobody knows. He also comes up with all sorts of apparently random rubbish, making him almost impossible to speak to; for example, he has a strange obsession with cheese, calling people 'good little rats', and makes references to a talking grapefruit called Stanley. Sometimes he decides that he is actually a dragoness called Annmarie. All of this somewhat perturbs his mate Epic Gold Rarity, who has waited years for a caveborn Vine to arrive so that she could continue her lineage, and is now wondering whether it would be entirely wise to unleash this mad dragon's genes into the Gold Tinsel breed...
