[Merlin's Heir]

Sixth foal is grown.
Because I want to keep manchado rare, this boy can only produce one (1) manchado foal, which can only produce one (1) manchado foal, and so on and so forth.
If bred with another manchado, only one of the foals will be a manchado, but the foal will not count towards the one-manchado-foal-per-horse limit.
In short, each manchado horse can only have one manchado foal. All of their other foals will not be manchado.
Except in the case of a manchadoXmanchado breeding, in which case the manchado foal in that litter will not count towards the one-manchado-foal limit.
This will keep it from becoming a common marking.

That doesn't make any sense. It will still pass on to offspring even if it's rare. Right?
Name will be Nevermore

The manchado markings can only be passed on to one of this horse's foals. Meaning, out of all the foals this horse has, only one of them will be manchado. Manchado is a not-quite-understood, very rare pinto-sort of marking in real horses. In Tiny Horses, I want it to stay rare, but if I let every other one of this horse's foals be manchado, then suddenly it'll be the most common thing ever because then all of those foals will have a bunch of manchado foals, and those foals will have even more manchado foals, and so on and so forth.
So, each manchado horse can only have one manchado foal. All their other foals will not be manchado.
This is to prevent it from becoming a common marking.
