Description

A scene from the Chamber of Secrets

76386 focuses on the moment the Polyjuice Potion goes wrong: instead of transforming fully into a fellow student, one character ends up with cat-like features after cat hair accidentally ends up in the potion instead of human hair. It's one of the best-remembered comic moments from the early Harry Potter books and films, and this set recreates it as a compact build. Rather than a whole location, a single humorous story beat gets its own small set here. The build focuses entirely on that one moment, rather than recreating a whole school environment the way larger sets do.

Four minifigures for a group scene

With four minifigures, 76386 is more figure-heavy than many small Harry Potter sets. Each comes with a wand and Hogwarts uniform detailing, and one carries the distinctive cat features from the failed transformation. That's enough to act out the scene on its own, without needing figures pulled in from other sets. For anyone building out small roleplay scenes, having the full cast included is a real advantage over sets with only one or two figures. The wands also differ slightly in shape and colour between the four figures, making it easy to sort and assign them correctly.

A stone bathroom setting in muted tones

The white, tan, reddish brown and light bluish grey palette recreates the stone walls and wooden fittings of a Hogwarts bathroom. With 94 unique parts out of 215 pieces, the build stays compact while still leaving room for sinks, stalls and wall panelling. The parts list on this page shows which brick shapes create that stonework look, useful for anyone building their own castle interiors. Individual wall tiles and floor pieces also work well reused in other interior or basement-style scenes.

Built for fans of a specific moment

Unlike the large Hogwarts castle models, 76386 zooms in on one clearly recognisable moment from the story. That makes it a good pick for fans who'd rather build out individual scenes from the books and films than collect one big combined model, adding new scenes to the shelf one at a time. For a shelf holding several small scene-based sets, 76386 fits in neatly alongside other moments from the film series.
