So I would love any input on this as I'm kind of at a loss right now and what I should do. I tried searching through other posts but have come up empty handed with my questions.

I have a ferus male I was looking to king, I got him relatively cheap and he had good stats so I put a lot of applicators and gb into getting him to where I want to be.

Well, my stud just popped out a perfect smilis that I would LOVE to king, but I like the looks of the ferus so much and don't want to lose all that gb and time I put into him, so I had the idea of making him king, and just replacing him with the smilus and keep his looks.
Now here's where it got confusing:
-I was told that if you have a mutated king and a mutated lion you want to replace him with, the Mutation gets passed on with the looks (so my smilis would stay a ferus)
-the ferus is dirty, but my smilis is clean and low Gen, but the lineage would pass onto the smilus
- the markings would change opacity once I put the looks onto the smilus

There's a lot of people agreeing and disagreeing and it's all really confusing, so if anyone has input or has transfered looks onto another king, I'd love to hear what you think before I waste 10gb on something I don't want.
Thanks in advance ❤
