GraviTrax Junior：恐龍小型入門套裝

My 3-year-old figured out the track connections on his own within ten minutes, which I honestly didn't expect. The dinosaur theme keeps him coming back to it way more than his plain blocks ever did.

The chunky pieces snap together easily enough that my 4-year-old builds whole tracks without help, and the dinosaur theme keeps him coming back to it. The marble roll at the end is a bit fast for tiny hands, but honestly that's part of the fun.

My 3-year-old hasn't put this down since we opened the box—the marble track pieces are chunky enough for his little hands, and he loves sending the dino down the ramp over and over. It's a great first set that gets him building without frustration.
