Happy Birthday Unicorn! is the kind of puzzle set that makes kids stop and stare before they even start. With two completely different illustrations on each side and five puzzles that grow more challenging as you go, this one has serious staying power.

Why Parents Love It

Start with the 2-piece cupcake - a perfect confidence builder for a newly minted 3-year-old, and then work up through the 4-, 6-, 8-, and 10-piece puzzles. Each puzzle is a small challenge that builds on the last, which means your child is developing real skills without ever feeling like they're being pushed too hard or held back.

Then flip the pieces over. The bold yellow-background portraits give way to a magical midnight birthday party. 2 completely different illustrated worlds in one box means this set stays fresh and interesting far longer than a standard puzzle.
