If you want, I'd advise Nano Puppy Family, you get to take care of 2 puppies, 1 male, and 1 female and when they grow up, mate them and have puppies! That comes with 2 games and in order to play it right, they both have to be running at the same time, when they have puppies, the puppies can go from 1 game to the other to visit mommy or daddy. It's sooo cute! or, if you want, you can get Nano Puppy and Nano Puppy Family.
I don't have either, but I'm getting Nano Puppy Family! If you need help PM me and I can help!
