A few have been fine or even good, but on the whole they’re stiflingly generic, seemingly designed to move merch rather than fit the ride. They don’t FEEL bayou-y - although I’m sure the Inagineers have detailed reports from New Orleans-based biologists to justify each one. The bears, foxes, rabbits, etc feel like they could fit into any vague Disney wilderness setting.
I’m no fan of Louis, but he offers a strong contrast - he’s a gator, perhaps the first animal people think of when they conjure up an image of the bayou. He’s also somewhat visually distinct, with his massive bulk a comical contrast to more standard images of cartoon gators.
Tiana’s swamp needed beasts that FEEL “bayou-y.” Add more gators, snakes, and turtles - an all-snake zydeco band would be a lot of fun. There’s a nutria in the film but none, it seems, in the ride. How about some herons or other wading birds? Make the setting distinct, don’t pack it with rejects from Brother Bear.
