Disney is infamous for waiting well after a movie is a hit before you see any acknowledgment of it in the parks.
Frozen was out of theaters, on DVD and already declining in popularity before we got any news about it getting a permanent presence at Walt Disney World.
We first saw Nick Wilde and Judy Hopps do a quick meet-and-greet at a media event promoting the film. Then we didn’t see them again at Walt Disney World until a month after the movie debuting. At that time, the two characters from the film joined the “Move It! Shake It! Dance & Play It!” but only made appearances on the floats with no type of meet-and-greet offered.
