I was thinking about this too, it would be cool if they added this in the norther area of the park between river and Everest. Have Brother Bear in there, if you want try pocahontas, throw in Bambi.If I had to choose, I would choose a North America section of the park. You can defo tie in some IP, I would go with a Gravity Falls themed attraction to once again hit on the Fantasy Aspect of the park or technically it could go the Dinosaur way too... both appear in the show!
Personally I still can't get over how there is not an UP ride btw, especially in a Central/South American themed land. Really hope they move the birds and meet and greet over there once done.
