How do you unlock games on littlest pet shop ds game?

Answer 1

as you are playing, in the corner of the screen there is a cloud bubble thing that has a picture of a game the pet you are playing as wants to play if you never seen that particular game, click on the bubble and there you go new games... if you have played that game before then push done or whatever. If you ever see a game you haven't seen before then click on the bubble and there you go new games even though I said that already.
