I am not sure if a thread or idea was discussed to plus MK's IASW or not, so I am basically going to put it down here:
The loading area will be as it is(even with the reverse layout), however,the back wall will look like a mountain and the cast member booth will have some rock work on the side, so as to transition into a cave(for the people watching from Pinocchio Village Haus, the other side of the mountain will a colorful waterfall.) Inside, we have the impression that we are underwater, because we can see Small World Mermaids(ones that don't look like Ariel) playing with toys(and saying hello from time to time) and having fun with a Sea Serpent(it will smile and a wink from time to time.) As we move further along, we see a happy octopus and squid, both of them holding a banner that says "what the current SW sign says", but just before we leave the cave, we see what looks like a toy version of the Nautilus, with a small black outlined cut out of Captain Nemo. From there, SW is the same, after the finale scene, when we reach the good-bye room, we see a big but sad (western or eastern style) dragon, wishing us good-bye and to come back soon. we exit and that is pretty much it.
