Well, I know the Okami x Xiu Mei breeding will basically look exactly like them (barring some sort of spontaneous mutation). So not too much of a surprise there.
Sinneca x Kylie I'm expecting a purple baby (since that's all that's genetically possible, I think?RryyBb), I think with some sort of benign white? and it'd be cool if she had Kylie's striped tail poof, though I'm hoping he/she takes after Sinneca for head/horn shape and the like. Side question, what is the difference visually between rRyybB and RRyyBB?
Sapphire x Mith...NO idea what to expect, haha. That's the fun of it, though!
