Any good games for a young girl?

Getting my sister a 3DS as a family for graduation and we were wondering if there are any good games out there for kids like her. Before you tell me to do my research, I did and I'm sure she'll love Nintendogs + Cats. She might also enjoy Pilotwings Resort and Cooking Mama 4 but I just wanted to know if there are any more games that you guys could recommend me. I showed her gameplay vids of those games and she thought they were "alright". Hoping to find a game that would be "amazing" but to no luck. Maybe I'm not searching hard enough :P She's currently addicted to Super Mario 3D Land and she loves Animal Crossing. She's a casual gamer that just likes silly, fun, and easy games. Any ideas would be appreciated, can't spend too much time searching around due to exams. Thanks!

Advance Wars : Dual Strike
Professor Layton series
Pokemon Black/White
The World Ends With You

These are good games to try out. Age is not an issue with these games so anyone can enjoy them.

Doers she like Pokemon? My nine year old son LOVES Pokemon Rumble Blast.

Give her the gift of funny: Mario & Luigi. :o

Graduation? When you say "young" girl, you mean...?

That Style Savvy sequel will probably be released here soon.

Try downloading Mighty Switch Force. Strong female lead. Fun platformer.
