You need a black pearl, which is rarely available.
You can submit as many coats/patterns as you wish...., but will have to pay to have them added to the game with a BLACK PEARL for each coat.
No, the foal will have a normal coat.
To create a coat on Howrse, you must buy a Black Pearl from the Black Market. After buying it, you may submit a coat. You must wait for a short period of time whilst Howrse accepts your coat and then anybody can use it with the Golden Apple.
Geor.
It's a horse coat color.
you can't you have to buy it
Ask in the 'Retired GA Coats' topic or the 'Howrse Spotters' topic in the events forum on Howrse.
you cannot have zebras on howrse but you can get a golden apple coat that is designed to look like a zebra
no but you have to obey the rules and have a black pearl
The Black Market page of the Black Pearl on howrse states that "You get 1 pass for every 5 players that pick your coat, limited to 40 passes by coat", so no. Not every time.
You cant you can create a coat. But no breed variations. My user name on howrse is 899bubble to add me as a friend!
Some what yes and no. Beacuse in a ratio on howrse the dapple gray coat is 7% witch means it is rare but not so much. Most common would be 12% and least common would be 2%.
