Description

Four minifigures, one party

With four minifigures, this set sits on the figure-heavy end for its size, opening up several roles straight away for a shared play scene: who's dressed as the unicorn, who's the fairy, and who's hosting the party? The 262 pieces split between costume pieces, decorations and small party props, so building alternates between figures and scenery rather than one long single build. That works well for playing with siblings or friends, since roles can be shared out instead of everyone crowding around a single minifigure.

Colours and the fantasy theme

The medium azure, white, bright pink and vibrant yellow palette spells out the unicorn-and-fairy theme clearly and gives a cheerful, easy-to-spot result on the play table. White and azure likely form unicorn elements such as a mane or costume parts, while pink and yellow carry the fairy and party decoration. This kind of colour combination turns up across several fantasy-themed Friends sets, so pieces from this set tend to blend well into a larger Friends collection rather than standing apart on their own.

Parts list and further play

Of the 262 pieces, 116 are unique elements, a reasonable spread for a four-figure set that leaves enough costume and decoration pieces for different combinations. This page carries the full, colour-sorted parts list, useful for tracking down a specific piece or reordering one, say when a costume element is needed for a dress-up scene with other Friends characters. That keeps the set useful well beyond the printed instructions, especially once pieces start mixing in with costumes from other Friends sets.

A compact build with room to grow

The set launched in 2025 and sits among the smaller Friends builds despite including four minifigures, making it one of the more figure-dense options at this price point in the range. With no vehicle or larger building involved, the build stays simple enough for younger children to finish most of it unassisted. Because costume pieces and decorations combine loosely rather than locking into one fixed layout, new outfit combinations keep turning up well after the first build. That keeps the Costume Party relevant beyond a single afternoon of play.
