What reviewers are saying

"The unusual 76386 Hogwarts: Polyjuice Potion Mistake rectifies that omission, faithfully recreating Moaning Myrtle's disused bathroom and containing four exclusive minifigures."

Ecosystem

76389 Hogwarts Chamber of Secrets — 76386 accommodates neatly with 76389, connecting above the slide which leads into the mysterious chamber. Minifigures can slot through the hole with ease and such continuity between sets is impressive. The consistent architecture is attractive, with identical 1x6x7 arch elements appearing in both sets.

4735 Slytherin — Versions of Crabbe and Goyle in 76386 are appreciated since those characters have remained absent since 4735 Slytherin was released during 2002.
