Unikitty Activity Book

The LEGO Unikitty Activity Book (set 853788-1) was released in 2018 to coincide with the launch of the LEGO Unikitty! building theme, which was inspired by the animated television series of the same name. Designed as an entry-level creative resource for younger fans, the set served as a cross-promotional tie-in that bundled a paperback activity book with a small, exclusive buildable figure. This approach followed a long-standing LEGO tradition of pairing character-driven narratives with physical elements to extend the play experience beyond standard construction sets.

The design of the included Unikitty figure reflects the aesthetic of the vibrant and whimsical show, utilizing standard system bricks to capture the character's signature expressive face and colorful appearance. While the activity book itself focuses on puzzles, mazes, and coloring pages intended for the preschool and early-elementary demographic, the inclusion of a proprietary character ensured that the item would appeal to collectors of the broader Unikitty line. It was generally received as a modest, accessible gift item that successfully integrated print media with the core building experience.
