Young witches and wizards join Harry Potter, Ron Weasley and Hermione Granger as they brew powerful Polyjuice potion. Drinking it transforms the characters into Vincent Crabbe and Gregory Goyle, which kids achieve by turning the minifigures’ heads to reveal an alternative face and adding a different hairpiece. The magic can go awry, however, such as when Hermione transforms into a cat! There are other surprises too: an exclusive, 20th anniversary golden Harry Potter minifigure; 2 random wizard card tiles to collect; and a secret tunnel beneath the sink. When this toy set for boys and girls is combined with LEGO Harry Potter Hogwarts Chamber of Secrets (76389), the secret tunnel connects the 2 rooms, expanding the play possibilities even further. This magical, modular system lets kids continue adding rooms to create an entire Hogwarts Castle model. The set measures over 3 in. (8 cm) high, 5 in. (12 cm) wide and 2.5 in. (6 cm) deep and makes a great gift for grandchildren. Contains 217 pieces. ## Features - Features a buildable Moaning Myrtle's bathroom famous scene to practice Harry Potter potion spells, with lots of authentic accessories - Kids transform favorite Harry Potter characters into Vincent Crabbe & Gregory Goyle, but sometimes magic fails and Hermione becomes a cat - Kids turn Harry, Hermione & Ron minifigures’ heads to reveal an alternative face, add a different hairpiece, and the transformation is done! - Includes Harry Potter, Hermione Granger and Ron Weasley minifigures, and 2 random wizard card tiles for kids to collect (out of 16 in total) - This LEGO Harry Potter toy for boys and girls makes a great gift idea for grandchildren and includes an exclusive, golden Harry Potter minifigure to celebrate 20 years of Harry's magic - This toy is one of a series of detailed modular sets that can be built, combined & rearranged to create kids' own Hogwarts Castle model ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08YPBK3TG | | Age Range Description | Adult | | Best Sellers Rank | #46,620 in Toys & Games ( See Top 100 in Toys & Games ) #1,493 in Toy Building Sets | | Brand Name | LEGO | | Color | Multicolor | | Customer Reviews | 4.8 4.8 out of 5 stars (5,894) | | Global Trade Identification Number | 00673419339735 | | Included Components | LEGO Building Elements | | Item Dimensions | 10.32 x 5.55 x 2.84 inches | | Item Type Name | Building Kit | | Item Weight | 11.36 ounces | | Manufacturer | LEGO | | Manufacturer Part Number | 6332781 | | Manufacturer recommended age | 7 years and up | | Material Type | Plastic | | Model Number | 6332781 | | Number of Pieces | 217 | | Size | One Size | | Sub Brand | Harry Potter | | Theme | Harry Potter | | UPC | 673419339735 | | character | Harry Potter;Hermione Granger;Ron Weasley;Anniversary Harry Potter;Vincent Crabbe;Gregory Goyle | ## Images ![LEGO Harry Potter Hogwarts: Polyjuice Potion Mistake 76386 Moaning Myrtle's Bathroom with Ron Weasley and Hermione Grainger Minifigures, Gift Idea for Grandchildren with Golden Harry Potter Minifigure - Image 1](https://m.media-amazon.com/images/I/81agsxGiJwL.jpg) ## Questions & Answers **Q: What age is this best for?** A: The box says 7+ which is based on how difficult the set is to build.
