76386-1 Harry Potter 2021 215 parts 8.5% repair risk Easy
The LEGO Harry Potter Hogwarts: Polyjuice Potion Mistake (76386-1) depicts the Hogwarts bathroom scene where Harry Potter, Ron Weasley, and Hermione Granger brew the Polyjuice potion. This 215-piece set features a brewing station with a cauldron. A play function enables minifigure transformations: turn heads to reveal alternative faces for Vincent Crabbe and Gregory Goyle, or swap Hermione's hair for a cat head. Below the sink, a hidden tunnel offers an exit, specifically designed to connect with LEGO Harry Potter Hogwarts Chamber of Secrets (76389), expanding the Hogwarts model. The set includes a golden anniversary Harry Potter minifigure and two wizard card tiles, integrating them into this modular Hogwarts section.
