LEGO Harry Potter: Harry and the Marauder's Map
The information hidden on the Marauder's Map is extremely useful to adventurous Hogwarts students like Harry. The heat from your fingers will make the details on the map appear, and when you use Harry's wand to unlock the hump-backed, one-eyed witch, she will slide backwards to reveal the secret passage to Hogsmeade. Includes 106 LEGO pieces.
