One of the many cool aspects of Disney California Adventure's Halloween decor is the transformation of the Carthay Circle Restraurant tower from its already-spooky daytime appearance with the "bats flying out the belfry" to a projection-mapped Oogie Boogie overlay with eerie greens and purples and a changing pair of scenes.  Combine that with the ghostly green lighting behind the bats at the top of the tower, and you have a really photogenic and Halloween-laden atmosphere.  Whether in plain view from Carthay Circle or framed between trees like this Grizzly Peak-originating scene below, it always looks bewitching! The Carthay Circle Restaurant tower is framed between trees in this Halloween Time evening scene.
