The LEGO Creator 3-in-1 Unicorn Castle (31175-1) invites builders to a realm of fantasy adventures. This 390-piece set features a magnificent castle structure, complete with four grand towers and two turrets, a charming bird house housing a single bird, a sparkling fountain, and a vibrant rainbow staircase. Within its walls, discover a diamond room and a celestial telescope, while a golden carrot adds a whimsical touch to the grounds. Accompanying the castle are three fantastical figures: a majestic white unicorn, a vibrant yellow Pegasus, and a graceful pink Pegasus. True to its Creator 3-in-1 design, the set offers versatile building options, allowing transformation into a unicorn ship model, distinguished by its rainbow sail, or a playful playground scene featuring a cozy forest cabin, a tranquil garden, and a small picnic table. This rebuildable approach provides varied display possibilities for the included mystical creatures.
