Donald visits a giant chess board with a talking red King and Queen. The Queen says Donald is "an Alice". (Donald is also dressed like Alice was in the 1951 film, and he has a wig like her hair.) When Donald escapes off the board, he bumps into a chest filled with pink candies that says "Hurry Eat One". When he does, he grows large enough to observe the chess board normally.
