Uncanny Valley: Gonzo taking a flash picture of the Happiness Hotel crew temporarily blinding all of them, shown with exaggeratedly dilated pupils. A funny scene and all, but it means that characters who usually have Eyes Always Shut such as Janice, Lips and the Swedish Chef suddenly have open eyes. Characters who have no actual eyes but wear glasses such as Bunsen, Zoot and Pops have the exaggerated eyes inserted into the frames of their glasses. Given this is the only time we have ever seen these characters with true eyes, it can be a bit unsettling.
Visual Effects of Awesome: This film outdoes The Muppet Movie's famous bike-riding scene by featuring Kermit and Miss Piggy sing a duet while riding bikes, going in circles and performing tricks in the process. And then it finishes off with an entire parade of Muppets on bicycles.
