 Out of the film's 107 minutes of running time, ten of the approximately 13 minutes of animation are at the beginning of the film. Lima tried to "cram every single piece of Disney iconic imagery" that he could into the first ten minutes, which were done in traditional cel animation (in contrast to computer-generated 3-D animation) as a tribute to past Disney fairy tale films such as Sleeping Beauty, Cinderella, and Snow White and the Seven Dwarfs. It was the first Disney film theatrically released in America to feature traditional cel animation since Pooh's Heffalump Movie (2005). This film, although quite different in terms of plot from any previous Disney film, also contained obvious homages to other Disney films of the distant past, such as Old Yeller, The Shaggy Dog, Swiss Family Robinson, Bon Voyage!, and Savage Sam. As most of Disney's cel animation artists were laid off after the computer graphics boom of the late 1990s, the 13 minutes of animation were not done in-house but by the independent Pasadena-based company James Baxter Animation, which was started by noted lead animator James Baxter. Baxter had previously worked for Walt Disney Animation Studios, bringing to life many memorable Disney animated characters like Jessica Rabbit (Who Framed Roger Rabbit), Belle (Beauty and the Beast), Rafiki (The Lion King), and Quasimodo (The Hunchback of Notre Dame).
