Just tweaking the ride's storyline so the FINDING NEMO characters are giving us - the guests - a tour of the undersea world, culminating in traveling through the real aquarium, would be a big step in the right direction.
I think there's a way to use both INSIDE OUT and WRECK-IT RALPH in the context of a larger, Figment & Dreamfinder-led Imagination ride that's more a throwback to the original incarnation. The IO characters could be used in a scene to visualize the makeup and organization of the human mind, from which imagination springs, while WIR could be used in a scene about how imagination is applied to creative endeavors like video games.
I love this idea!
One of the insiders on Magic said there will be a "significant entertainment offering" inside there, while
@Marni1971 has said we shouldn't expect anything that could be qualified as an "attraction."
So I really don't know what it's all going to be. I'd expect there'd have to be
something behind that city facade.
