Dagron creatures are usually fluffy, serpent-like fellas with dragon-like front feet.
-no, they don't breath fire, but depending on the subspecies they can be resistant to fire, ice or accids-
Ground dagrons are mostly fire resistant subspecies, they like warm places (they can be often found sneaking in and sleeping in unguarded campfires), but depending on their environment they can have the less common ice or accid resistence instead.
These dagrons make good companions, since they don't get too scared around people and they get used on humans pretty easily, but they can sometimes get a little too clingy.
They can't really be all described the same way, because ground dagrons have each their own personality, some are terribly stubborn, some are very playfull, some lazier or just like to keep things chill and others will get in every trouble that isn't even possible.
They are good climbers, whether it's trees or rocks, they can move around quickly and with ease.
Ground dagrons can have variety of different features like horns and spikes, large fangs, feathers/feathered parts of body, scales/scaly body parts.
