Waterhorse Dragons received their name due to their horse-like physique and endearing behavior. They are capable of surviving out of water, and when on land their skin secretes a gelatinous goo to retain moisture. However, their large paddle feet are better suited for swimming, and waterhorse dragons tend to move very awkwardly when on land. Waterhorses are very friendly dragons and enjoy playing with humans.

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.

Ronald Bruce isn't the sharpest knife in the drawer, and he's a bit of a kleptomaniac. He's particularly fond of the red boots that the dinos wear. They're good at holding water, at least for a while. He also thinks they'll help him be able to walk better on land than the average waterhorse. Where his lack of smarts comes in, is that he's always trying to swipe boots from 9DIN0, the gold dragon who thinks he's a dino. Where every other dragon in the cave knows that 9DIN0 really is a gold, no matter what he says, Ronald Bruce believes 9DIN0 and consequently cannot figure out why there are no red boots for him to steal.
