On a night with a blue moon filling the sky, a moon fairy named Moona appears outside the Blue's Clues house and tells Blue a story about her birth under a blue moon, with a key that will unlock her greatest gift. We follow Moona to find this key and once we have it, a great hunt all over the Blue's Clues house begins to find the lock that it fits. Once that's found, the key unlocks ""Blue's Room,"" a special playroom where she is transformed into a puppet. Here, Blue can meet lots of new friends, but the most important thing about it is that she can talk. We take part in games such as ""Boogie Woogie"" (a freeze-dance style game) and ""Dress-Up"" and then a clock chimes and Blue returns to Joe, who is excited to hear about her greatest gift.
