Review on LeapFrog Blues Clues Handy Tracker by Jim Kriegshauser

I bought two sets of Blues Clues, School and Train thinking my son could use the Smart Blocks in each Smart Cube as advertised. Well, that's not entirely correct. The Blues Clues clue blocks ONLY work as intended in this Smart Cube. When we plugged them into the other Smart Cube that came standard with the car, they all made slight singing noises and nothing else. Once upon a time they really worked in it. Which is frustrating. Also, it's a cute toy and fun to play blues clues with the dice. The volume is a bit quiet even at the highest level. But my son seems to like it. It comes with its own clue blocks so it can be played without other sets.
