Breeding Poo and Poo can work, but the most likely chance is that it will produce more Poo dragons. I suggest you breed Gummy dragon and Cool Fire Dragon since I already got a Crystal Dragon and Mirror Dragon from this combination.

A little bonus: For you to have Soccer, just breed an Alpine and Medieval dragon. (Or 2 Cool Fire Dragons)
