Professor McGonagall shape-shifting into a cat from Harry Potter and the Prisoner of Azkaban for the Game Boy Advance. The smooth color change in this animation was accomplished by tweening the character's palette in time with the animation. Both sixteen color palettes had to be compatible with both the woman and the cat. In the raw animation file, the cat ends up with a flesh-tone face, green legs, and still wearing her spectacles.
