You see, Walt Disney's on ice for real, chilled out, a genuine stiff at -180 Celsius. Humorously enough, despite Mr. D's willingness to trust a bunch of lackeys with his cadaver, was afraid of the Long Sleep. So he had his scientists create a sensory link between himself and an employee of the park, one fairly innocuous man whose job mandated he skulk through the bowels of the park. Order and uniformity, that's what Disney liked. And so, he kept watch.
The guy, whose name isn't important here had a card implanted in his skull and all he could think were Disney's thoughts and all that he saw, Disney saw.
