Fans of Harry Potter can now reenact the scene of Harry, Ron, and Hermione encountering the mountain troll in the bathroom at Hogwarts. The menacing troll is holding a large club and is dressed in his fabriclike loincloth with vest, while Harry is wearing a black robe and holding his magic wand. Tilt the shelf underneath the bathroom sink and it will fall over, adding realism and fun to the scene.
