Is a face star considered a mutation? I'm asking this because I was hoping to breed a seed pony with a face star, eventually using my Streakin fert for the new seedling. I'm not sure if that's possible, as no existing face star seed ponies reveal any other mutations.
As far as I know it doesnt matter. But the face star only passes to the next kid, nothing past that. So Strider will pass it but none of his 4 kids will.
I'm speaking about Strider, of course. ^^
I'm probably going to request your permission sometime tonight. Wee!
Vanyel is correct. Strider passes his star, his children do not pass it. It is NOT a mutation, so feel free to fertilize to your hearts content

Thanks for the confirmation, Tari!

Sounds like everyone has it right!
