This Mudpuppy puzzle is double the fun for kids around 4 years and up. First, they get to build a super colorful and wacky 64-piece jigsaw puzzle showing cats and animals having rocket adventures in outer space – it's really cute and engaging art. Once the puzzle is put together (it finishes at a nice 23 x 15.5 inches), the fun isn't over! All around the border of the puzzle picture, there are over 40 little space-themed objects and animals drawn. The challenge is to find every single one of those items hidden somewhere inside the big puzzle picture. It's a fantastic way to keep them playing and practicing their observation skills long after the pieces are connected. The pieces are sturdy, the box is nice for storage, and it's a perfect screen-free activity for a rainy day, playdates, or family game night. Mudpuppy makes great quality, creative toys, and this puzzle is a hit. Great as a birthday gift, holiday present, or just because. It's challenging enough to be satisfying but not so hard that it's frustrating.
