About LEGO Costume Party with Unicorn & Fairy
A 261-piece building kit creates a vibrant costume party scene complete with DJ booth and dance floor. The set centres around a party venue where minidolls can gather in their fancy dress outfits, providing a detailed backdrop for imaginative play scenarios.
The kit includes four minidolls - Autumn, Olly, Leo and Paisley - along with two animal figures that can be dressed as various characters including a bumblebee, merman, magician, bunny, fairy and unicorn. Each character comes with specific costume accessories to support their themed appearance.
Party Features and Accessories
The set provides extensive party equipment including a slushie machine, cakes, drinks, balloons and party hats. Additional role-play accessories include a merman's trident and fairy wand, giving children multiple story elements to incorporate into their play. The DJ booth allows one character to act as the party host whilst others dance and socialise.
The completed model measures 8 cm high, 25 cm wide and 5 cm deep, making it suitable for tabletop play. Designed for builders aged 6 and up, the set focuses on social play scenarios and costume-themed storytelling rather than complex construction techniques.
