My theory is the fantasy aspect.  Disney represents one of the last vestiges of "magic" left in the world.  That combined with the fact that no matter your age, you grew up with a Disney catalogue.  So these fats are in a place where memories of the last time they were human are triggered by visual and audio stimuli combined with the wondrous aspect of "Disney magic" allows them to fantasize about being regular again.    The immense numbers of whale pods there just help reinforce this vision.
