The contest has ended, as all secret horses have been found! Thanks to all who participated!
- Zebra - Having no special traits (horn, wings, big size, etc.) causes this mutation to happen.
- Red-winged Blackbird - Horn, wings (big or tiny), big size, and flaming hooves cause the Destrier hide gene to mutate to the Red-winged Blackbird hide gene.
- Rainbow Smash - Horn, wings (big or tiny), big size, and flaming hooves cause the Unicorn hide gene to mutate to the Rainbow Smash hide gene.
The remaining two mutant breeds work just like the Red-winged Blackbird and Rainbow Smash breeds - except they mutate the Nightmare and Pegasus hide genes.
That's two more prizes remaining! Good luck!
