It has a much better gallop graphic than horses, which should be updated.
The stats are just that of a horse, with higher taming skill needed.
I have no official information on this mount, so feel free to change it as you see fit.
Personally, I will probably make mine a nice pet to have in battle once I mess with it down the line.
Add this to your shrink .cfg, be sure to use the tab button in between.
