A Cowbra horse on Howrse is a divine species. He looks like a horse rearing with a long snake tail. There is only one, with unmatched strength. He has NO ranking, but he is the absolute best howrse. There is no way to obtain one.
It's luck. Sometimes you find one, sometimes you don't. Keep putting horses in the box for as long as you can and eventually you'll find one. ~Camigurl on howrse if you want to friend. :)
When you have been on Howrse long enough you can buy a Horse from the auctions or Private Sales
as long as a real year if you don't age your horse if you age it makes your horse 2 months older automatically
12 months, (6 real-time days).
