How do you breed in viva pinata trouble in paradise

Ok while breeding you pinatas you will do a little mini-game. after you do it so many times (7 to be exact) you will get a chance to get a twin bonus. To do this you must finish the game fast, you will make a twin and get an achievement! Also during this same run (doesn't have to be the same one) try get all the hearts too, this will get you a wild card and another achievement!
