Going for?

I have enough monkey teeth to get it. And I just wanted to know how much GB it would be worth, since I'm kind of impatient and I don't want to wait to buy a bunch of lion scrotums for GB next month ^^;

But I'd also use the GB I get to get a king with the same mutation as my current boy. I do NOT want to change his base or mane, I just want him to get better stats. No one will stud him as he is now.
