The Wubbox part I personally do not agree with (even though I have an idea on how it could work) but I feel like the other bits would come during Anniversary Month
Update, I should probably explain how you actually get the hexes. Basically if you try to breed a hex it just turns into Wubbox after a successful try, but when you get all of the quints (all 21 of them) you unlock the Hexifier, which allows you to attempt to merge 2 monsters to make a hex :D
