Description

Four characters in a small set

Four minifigures is more than you'd expect from a 189-piece set, which points to a scene built around several characters rather than a single large structure, likely ghost hunters facing off against something stranger. That balance between figure count and piece count shows part of the set was deliberately set aside for character variety and roleplay rather than a big build. It's a good fit for anyone who likes playing with several minifigures at once rather than building one large model.

An app-connected theme

Hidden Side pairs ordinary LEGO builds with a free companion app: point a phone or tablet at the finished model and augmented reality adds extra ghosts and interactive elements on screen. Set 70427 works as an introduction to that idea in a smaller, more affordable package than the theme's bigger builds. The set still works perfectly well as a standard build-and-play model for anyone who'd rather skip the app altogether.

A cool, slightly eerie palette

Black, light bluish grey, dark bluish grey and a striking medium azure give the set a cool, faintly unsettling look that suits the ghost theme. Medium azure stands out as the signature accent colour across the Hidden Side range, often used for ghostly or supernatural effects. With 92 different elements among 189 pieces, the share of unique parts is high, suggesting plenty of small detail work built into the haunted scene.

Parts for spookier builds

The full parts list on this page covers all 92 different elements in the set, a useful starting point for anyone hunting for colours to suit a spookier or darker build of their own. The medium azure pieces in particular work well as lighting effects or unusual accents in other models. Anyone starting out with Hidden Side will also find this a handy overview before moving on to larger sets in the range, since the colour palette carries across the theme.
