Without purchasing a Chest, or a super Roo itself, what is your best discovery, and Roo so far in the game as we go along?

Me? I got a dominant giant trait and short tail trait that are both dominant and typically pass, I breeded them both together to make a giant/short tail ursine, and am breeding it with a 5th gen to make a 6th gen. It had a size giant 14.0 in the family also as I been breeding them down, but it came down to 12, because I haven't paired it up with other giants, however.... I had an accident of it breeding with a wrong roo, instead of making a 6th gen it made a 5th gen because it breeded with a different Roo which was a 4th Gen giant Red, luckily it gave a Giant 14.0 again, along with the short tail...... And I now put the mother Giant/short tail ursine 5th gen in its own home with a Whine that is 5th gen to make the 6th, and my Giant Red is back to breeding with the other Red with Orchid Clear eyes, the first two babies they had both reds gave me an Autumn, you would think matching two reds would result in a red, but no, I got an Autumn twice, then the accidental breeding with the Giant Red, and Urssine lol....

So I guess my best Roo would have to be the Giant 14.0 Short Tail whine that my Giant Red and my Giant Ursine/short tail gave me, but my favorite roo is my Red with glacier/clear eyes that I own, and will convert into a meepet.

So, what is your best roo that you have gotten?
