Haven't seen it. Mostly I've been really impressed with the level of quality in Disneyland as of late. On my last trip to DCA a couple weeks ago, I couldn't believe how many lights in Paradise Pier were burned out, missing, or just hanging on by a wire.
I guess you just can't get everything perfect all of the time.
Guests do see how the treehouse looks, I don't think the retired ball pit for kids is even really an issue anymore since it's been gone for years along with the slides.
The feeling I get is the treehouse is in the back corner of toontown, so out of sight out of mind for repair. It's just bad show is all, I wanted to bring attention to it since alot is being fixed at the resort.
I think the reason it's falling into dissaray is because the area has lost most of it's luster and I'm sure execs are trying to decide what to do with that corner of ToonTown.
As many have suggested, I would love to see the lagoon, Gadget's Go Coaster, Chip N' Dales, Mickey, and Minnie's house removed. In that back corner would be a new darkride. Now, the front of the show room still needs to be disguised, so a facade of Minnie's house with a meet and greet station would be there, as well as Chip and Dale's tree above Mikcey's house. Mickey's house would serve as the que for the new attraction.
The attraction itself? Well, I started to like a basic idea someone else suggested, but here's my version of their great idea. Pete has broken into Mickey's film vault and stolen the cannisters of his early work. With a new projector Pete has aquired, he can actually go into the films and help himself be the victor in all his conflicts with Mickey, making Pete the top dog..er..cat..in ToonTown.
So you start off in Mickey's garrage and hop into his car. The car is trackless and capable of movement (like the Hunny Hunt vehicles in TDL). The first room has Mickey tied up in film and he tells you about Pete's plan. The next room has a projector lighting up the screen with one of Mickey's cartoons. Pete is standing on a platform with a laser-type contraption aimed at him. He tells us we are too late and boom, fog shoots up around him and he dissapears. Suddenly he appears on screen and takes off. The laser then moves to us and our vehicle starts to rock and shake as fog shoots up around us. When the fog clears, we find ourselves surrounded by cartoon scenery and a large screen that has the last room being displayed on it. From then on it's a serries of rooms where we encounter classic Disney cartoons while trying to chase Pete. Along the way we cross classic characters from Donald and Goofy to Clairabelle Cow. The vehicles moves differently in certain scenes, such as "Plane Crazy" or "Steamboat Willie." I think it would be really interesting to reorchestrate the themes to these cartoons, but in a more cinematic style to match the action in the ride (kinda like what Indy did).
The only problem I see for such an attraction is that ToonTown closes early. Why put all this money into an attraction that is in an out of the way location that isn't open alongside park hours?
