In this episode, Joe has something very special for us. He's created his version of Blue's Clues known as ""Joe's Clues,"" in which he leaves orange handprints on the clues and he wants us and Blue to play along. We have fun searching for Joe's Clues, solving riddles and turning many of the program's customs upside-down along the way. Later, in ""Blue's Room,"" we play Polka Dot's Puzzles with Polka Dots.
