Whisper of the Heart, Howl's Moving Castle, Spirited Away, My Neighbor Totoro, and Castle in the Sky, are my favorites, in that order. Although, it's a reeeaaaaally close race for my favorite, because I LOVE pretty much all Studio Ghilbi films.
You mean Heen? I love him because he is so old and lazy! She had to carry him up all those stairs reminded me of when I first got my puppy and she never climbed up stairs because she was too fat so I had to carry her!
