What Makes this set WOW?
Character Transformation Mechanism: The set includes double-sided heads and alternate hairstyles, allowing Harry and Ron to instantly transform into Crabbe and Goyle. A unique cat head element for Hermione is also included, allowing for a faithful recreation of the iconic scene from the film.
Hidden Entrance to the Chamber of Secrets: The center sink in Moaning Myrtle's bathroom lifts on a hinge to reveal a functional opening with a tunnel. This function allows you to physically connect the bathroom with the slide in the larger Chamber of Secrets set (76389).
Collectible Gold Minifigure: The set includes an exclusive, all-gold Harry Potter figure on a dedicated base. It was released to celebrate the 20th anniversary of the LEGO Harry Potter series, which is a great value for collectors at such a low price of the set.
Modular construction system: The construction is based on a rectangular section with Technic pins, which allows the bathroom to be easily attached as a floor anywhere in the castle. This allows for full personalization and expansion of the Hogwarts model with additional compatible rooms.
