I saw this movie in the 1990s, not entirely sure if it was made in the 1990s though. All I can remember is it had a human painter, talking animals, and a scene with dancing, singing mushrooms. Any help is greatly appreciated!

Could it be The Elm-Chanted Forest (1986) His name is peter http://www.amazon.com/Elm-Chanted-Forest/dp/B00000IYR6
