To light for sable... I was looking for kind of Yb belly... or clear belly... that are good indicators that something is goin on..
As of YB unlocking stuff..
There is new morph now in game i saw it on Ben Siegel Facebook..
Is called Highway Ball Python.. and that's cross between dinker and Yb and is totally insane... so YB is one of this morphs always good to have... and Probably this is why YB females are still expansive even if they dont look much
