Heartlake City Brick Box
41431-1 Friends 2020 336 parts 1.6% catalog rarity Intermediate
The LEGO Friends Heartlake City Brick Box (41431-1), with its 336 pieces, offers a 6-in-1 building concept for varied constructions. Three Heartlake City scenes are assembled, each transforming into an alternate configuration. A café playset takes shape, then rebuilds into a wading pool. A music shop converts into a DJ booth and performance stage. Finally, a horse park appears, later transforming into a treehouse playset. These scenes connect, forming a hangout area where the Friends girls and their small toy animals gather. The set's rebuild functionality provides continuous play within the Heartlake City universe.
