Yayyyy!

I've seen Spirited Away, Princess Mononoke, Kiki's Delivery Service, My Neighbour Totoro, Castle in the Sky, The Tale of Kaguya-hime, Grave of the Fireflies (I think I fell asleep for part of this though), Howl's Moving Castle, and From Up on Poppy Hill... And I think that's all of them. Also, there was Mary and the Witch's Flower, which I thought was Ghibili but actually isn't. Wow.

Anyway, great movies; classic, go watch them if you haven't seen them before! They're all really interesting and creative in their own ways. :) 

I've seen My Neighbor Totoro (I even have these adorable Totoro socks!!), Kiki's Delivery Service (pretty sure), Howl's Moving Castle (more than once), Sprited Away (I think), and some others, i'm pretty sure. @Jaybells, I also saw the Mary and the Witch's Flower (and thought it was Studio Ghibli)! I think I've seen a handful which were similar to Studio Ghibli, but were not made by them. But yes, they are really good! Especially Totoro!! YAY
