My six-year-old was so proud when the legs started moving on their own after we finished snapping everything together. Watching it crawl across the kitchen floor made all the careful building worth it.

My son spent a whole rainy afternoon snapping this together, and the moment he set it down and watched it actually crawl across the hardwood, his face lit up. The gearbox assembly is simple enough for a 7-year-old to manage with a little help, and it moves surprisingly steadily.

The little gears click into place so satisfyingly, and watching it scuttle across the kitchen tile on its own after we finished the build was genuinely thrilling for my 7-year-old. It took us about an hour of focused tinkering, and the way the legs move is surprisingly lifelike for such a simple kit
