I'd like to see upgraded animatronics of course. Also upgraded and more subtle lighting. Like how you rarely see lights, ceiling and infrastructure in pirates.
I love the toad relocation idea. The same could be done for Peter Pan as instead since it too is a very popular dark ride with a ton of potential. Plus it would be a perfect place to make an old london sub land in the future to include the mary poppins dark ride I've been begging for.
