Built from 390 pieces, this Creator 3-in-1 set offers three different unicorn-themed builds using the same bricks. The main unicorn castle measures over 23 cm high, 19 cm wide and 11 cm deep, featuring four towers and two turrets packed with fantasy details.

Each of the three models comes with the same trio of unicorn figures: a yellow Pegasus, pink Pegasus and white unicorn. The castle build includes a bird house with bird figure, rainbow staircase, fountain, diamond room, telescope and golden carrot. Alternative builds transform the pieces into either a unicorn ship or unicorn playground, though only one model can be constructed at a time.

Castle Features

The primary build centres around the multi-tower castle structure with its distinctive turrets. The rainbow staircase connects different levels while the fountain and diamond room provide focal points for imaginative play scenarios.

Designed for builders aged 8 and up, the set follows the Creator 3-in-1 format where the same piece collection rebuilds into completely different models. The alternative ship and playground configurations use the full brick count to create equally substantial builds with their own unique play features.
