LEGO Minecraft The Sky Tower (21173) is filled with authentic action and diverse environments that kids with a passion for Minecraft can reconfigure again and again for endless adventures in the clouds. Kids use cool, authentic Minecraft features to fly into the sky and build a floating blacksmith’s house, a soaring tower, and a garden island. The play possibilities range from growing vegetables to battling flying phantoms. This accessory-packed playset is infinitely reconfigurable so kids can rebuild, reimagine, and enjoy endless adventures – just like in the online game, but with hands-on, creative construction.
