I don’t know what this is but I like it.
They used the Adventure Time characters and put them as characters in Miyazaki movies (Top to bottom: My Neighbor Totoro; Nausica-Valley of the Wind?; Spritied Away; Howl’s Moving Castle; Kiki’s Delivery Service; Ponyo)
I’m not sure about the yellow dude at the bottom - he may be a part of Ponyo. I haven’t seen that one yet.
