This is stuff from way back on page one, but I don't think they were ever addressed....
Animation studio was totally ripped out and the interactive area and Animation Academy is there now. And Sounds Dangerious is suppose to operate seasonally, but the last time I as there during a holiday, when it is usually open, it was not. I don't think it may ever re-open. There was another topic on the board about a rumor it might be getting turned into a Phinus and Ferb attaction. Rumor, key word.
There is still a peice of the ORIGINAL Backlot Tour that stands abandoned and waiting to be used. It was a part of the original super long tour. It was then was split up into two tours, Backlot Tour which still opperates, and Backstage Pass which spanned from right next to the Backlot Tour to where Journey into Narnia now is. It was made up of three soundstages and while stages 2 and 3 are now Toy Story Mania, soundstage 1 is still empty. You can see the outside of it right past
Pixar Place. It has a large sign out front that says "HOT SET."
There is another area from Backstage Pass. It wasn't a soundstage, but a warehouse similar to the prop house on the Backlot that was the start of the walking tour. I remember that area myself.
It held additional props and they had a section where they picked someone from the tour to ride on the bumble bee from "Honey I Shrunk the Kids." A friend of mine worked in that area and told me the room is still there, exactly the way it was when it was open. She could have been blowing smoke though. I have not seen it myself and it's in an area closed off. Even if the stuff isn't there, the building is there. That I am sure about.
As for Pocohantas and her Forest Friends... the area is open seasonally as a dance party location. They call it "Good Times Gathering Spot" but it's usually only open during major holidays. Many characters relocate there, Pocohantas hosts a story time, there is a DJ, and Gi-tar Dan moves there as well.
