It is a time of celebration at Disneyland for it is the 55th anniversary of Mickey and Minnie's relationship. After the park closes for the evening, Winnie the Pooh, Tigger and many other characters come out to celebrate the happy occasion. Unbeknownst to them, however, Queen Grimhilde, in her Castle of Sorrow, dislikes the idea of happiness and asks the Magic Mirror, "Magic Mirror On the Wall, tell me who dares to be more full of happiness than me." The Magic Mirror informs her of Mickey and Minnie's celebration, displeasing her. She plans to end their happiness before midnight.
