LEGO® Harry Potter™ Hogwarts™: Exchange potion mistake (76386) is a fun inspiration for magical adventures in the restroom at Hogwarts.

Young witches and wizards can join Harry Potter, Ron Weasel™ and Hermione Griffel™ in brewing a powerful changeling potion. Have the characters drink the potion, turn the minifigures' heads, give them different hair and watch them transform into Vincent Korzel and Charles Brush. But be careful, because things can also go wrong.

For example, Hermione is suddenly a cat! The set includes even more surprises: an exclusive golden anniversary minifigure of Harry Potter, 2 random wizard card tiles to collect and a secret tunnel under the sink. When you combine this set with LEGO Harry Potter Hogwarts Secret Room (76389), the secret tunnel forms the connection between the 2 rooms for even more play possibilities. This magical, modular system allows kids to create their own model version of Hogwarts.
