Let kids’ imaginations run wild with the LEGO® Friends Costume Party with Unicorn & Fairy (42661) set—a creative building kit designed for girls and boys aged 6 and up. Bursting with storytelling inspiration, the set includes 4 LEGO Friends mini-dolls, plus a cat and horse figure, all ready to take part in a whimsical costume celebration. The friends dress up for the occasion: Autumn becomes a bumblebee, Olly transforms into a merman, and Leo plays magician while Churro the cat dons a white bunny costume. Meanwhile, Paisley turns into a fairy, and Periwinkle the horse becomes a unicorn, adding even more magic to the scene.
The party comes alive with interactive elements such as a stage, DJ booth, and snack table, as well as a photo booth with fun accessories so the characters can strike playful poses. Packed with colorful party props—including a slushie machine, cakes, drinks, balloons, hats, a trident, and a fairy wand—this set encourages kids to invent stories, act out social situations, and explore friendship dynamics in Heartlake City.
Perfect as a birthday gift or a just-because surprise, this 261-piece playset brings hours of fun and imaginative role play. Kids can also enjoy digital building support through the LEGO Builder app, where they can zoom in, rotate models in 3D, track progress, and save their sets as they go. Once built, the main model measures over 3 in. (8 cm) high, 9.5 in. (25 cm) wide, and 2 in. (5 cm) deep, making it an engaging centerpiece for imaginative adventures.
