I need your help~!

My cousin wanted to watch some anime but all of my anime are inappropriate for her age. She's 12 and she's not very open minded so I thought that giving her the anime I have would be a bad idea. She'll laugh about a single mention of anything she thinks is impertinent or perverted. It's giving me a hard time picking out an anime for her.

So, does anyone here know any anime that's suited for a 12-year old girl? Anything without ecchi, kissing, nudity, fan service, yaoi or yuri? And something not too complex for someone like her to understand. I really wanted to give her an anime but I don't know anything like that that she haven't watched.

BTW, she already know these anime:
~Prine of Tennis
~Cardcaptor Sakura
~The wallflower
~Sailor Moon
~Inuyasha
~some Naruto
~The wolf children:Ame and Yuki

Please help me~! Onegai minna.
