Brandy, Dana's little sister, is having her birthday coming up a week before Easter. She cons her parents into setting up an egg hunt for her birthday, but during the party, an egg fight ensues and the party becomes a disaster. During the egg hunt, Dana finds a strange, large, pale green egg, which does not break when it is thrown by Dana's best friend Anne, much to Dana's amazement. About a day after the egg disaster, the huge green egg hatches and out comes an "egg monster" that resembles a pile of rotten scrambled eggs with eyes.
