Appaloosa.
The answer you are probably looking for is the Appaloosa - however you are confusing a horse breed with coat patterning, though the two run hand in hand as the colour of a horses coat is controlled by its genes. The gene responsible for spotting is the Leopard Complex (Lp) and different spotting patterns happen depending whether the gene carried by the parents is homozygous(dominant or recessive) or heterozygous due to the Lp gene being incomplete. A horse's coat pattern that has a spotted rump is known as a blanket spot but other spotting pattens include leopard spot, snowcap, few spot and snowflake. The Lp gene is also responsible for other characteristics such as stripey hooves, white sclera and skin mottling. Other breeds of horses also have the Lp gene - notably the Knabstrupper and the English spotted pony.
On the game Horse Academy on Facebook, If you want to create a "specialty breed", you have to match certain horses to get them. For example, If you want a BLACK BLANKET APPALOOSA: Breed 2 black piants together BROWN BLANKET APPALOOSA: Breed 2 brown paints together I have also discovered how to create the Tiger Horse, and a silverish colored hose with the rare white or golden mane. I still have not yet discovered how to make the pink or green tinted horses. I am still experimenting with that one.
Get a president jockey, and just breed with a vitamin
breed a male white Zebra and a female cream zebra
Most horses with a white rear (called a blanket) are Appaloosas.
get the male horse a white zebra and the female horse a cream zebra then breed using the 30% vitamun
chances are you will get a black horse with white small white specks.

White
It's a paint horse. A black and white paint horse.
for a blanket appaloosa, heres the formula. brown: two brown horses with the white paint gene black: two black horses with the white paint gene. the mane and tail colors don't really matter. DO NOT CHANGE THE COAT OF A SPEC. BREED BECAUSE YOU CANNOT GET IT BACK AFTER!
The Friesian Horse. Black with very little or no white markings.
