I second Avatar. I was thinking about MLP.
The Last Airbender, Star Wars: Rebels... My Little Pony if you need to.
Third'ing TLA and My Neighbor Totoro! Also was thinking about MLP but that's limited per country.
Forgot some great shows I watched when I was younger. Maybe a bit of Land Before Time (if it's possible), and Spirited Away (though if she's unfamiliar with a cultural context of spirits, it may scare her like it did my 12 yr old niece x3 Especially No Face and the transformations); Vec and Cado suggested shows in the Studio Ghibli genre, maybe you'd like to take a peek there and see which could best fit the times.
I'd personally add Princess Mononoke but I may be a bit silly with the violence and blood.
But if you're going for Ghibli...not Grave of the Fireflies until a LONG WHILE LATER.Maybe Phineas and Ferb? Recess? Early seasons of Spongebob? The Wild Thornberrys?
I'm recalling most of those shows I watched in the 90's or early 2000's. ._.
OH!
If you're going for movies, I'd really suggest The Dark Crystal and Spirit: Stallion of the Cimmaron. The former for its great musical scores and a bit of animated fun, and the latter for...a lot of reasons.
The Hunchback of Notre Dame?
The Iron Giant?
Toy Story?
The Prince of Egypt?
An American Tail?
How to Train Your Dragon?
Mulan?
oooo, Fantasia? (If you're into music as a parallel to the show?)
101 Dalmatians?
Finding Nemo/Ratatouille?
Also, add Princess Tutu, which despite the name is pure excellence.
omg you too. YES THIS! :3
