Description

An everyday scene, not an adventure

Rather than a travel or adventure theme, 42645 focuses on a domestic moment: the playroom belonging to Aliya's baby sister. Scenes like this sit at the heart of the LEGO Friends range, which regularly puts family, friendship and care at the centre of its sets. For children who enjoy acting out family moments, this gives a direct link to their own experiences with siblings or babysitting, rather than a fantasy or far-off setting.

76 unique elements in just 125 pieces

76 unique elements out of 125 total pieces is a notably high ratio for a set this size, translating into plenty of small furniture pieces, toys and room details rather than a handful of large, repeated blocks. That density makes the build more varied than larger but more uniform sets. The full parts list on this page shows exactly which shapes and colours are used throughout the finished playroom. Anyone collecting individual furniture pieces will find this list worth checking closely.

Three minifigures for shared play

Three minifigures allow for scenes with several characters at once, likely including Aliya, her baby sister and another figure from their circle. That opens up role-play possibilities around babysitting, playing together or everyday family life that extend well beyond simply building the playroom, keeping the set interesting and playable long after construction itself is finished. The room's furniture and small toy pieces can also be rearranged, keeping play fresh over repeated sessions.

Yellow, orange, white, green

The friendly colour mix of yellow, orange, white and bright green gives the set a cheerful, child-appropriate look well suited to a playroom setting. Yellow and orange likely cover warm furniture or toy pieces, white serves as a neutral surface, and green adds fresh accents, possibly for plants or additional toys scattered around the room. This palette also sits comfortably alongside other sets from the wider Friends range, making it easy to display together.
