Snow: A Divine horse that can breed, but only with the mist Divine. The coloring of the Snow's name indicates what competitions he will excel at. These Divines cannot be sold.
Sleipnir: My personal favorite! Sleipnirs have 8 legs, and come in black, fire, white, and brown. They have 1500 skills. They can be sold, but usually sell for millions.
Gypse: A Divine horse made of sand, he turns into sand every night (creepy, yes) and the owner can exchange the sand for skills. They can be sold, and sell for 1-2 million.
Mist & Ocean: Mom and baby! Mist can change her skills, and therefore her foal, Ocean, can too! Ocean's dad is the Snow horse. These two cannot be sold.
Croesus: Produces passes instead of manure! Each month, a horse named Junior Croesus turns into a Croesus.
Xanthos:A Divine that gives energy points to a horse, and possibly a HoP if you stroke it!
Uh, I think that's all!
