Congrats! If there's nothing else you really can do then I guess you'll just have to settle with having your perfect piggle. You could put him in your house as a nice decor.
Maybe try hatching him with other types of piggies so you can have a barn full of them? Or, maybe hatch with the same type or different type of piggy and try for different talents?
Hi! Well, now that you have a perfect piggle, why don't you enter him in some pet derby races? You could win lot's of arena tickets, and it's also lots of fun :)
