The HEXBUG Nano Zip Line Starter Set unlocks new possibilities and nearly endless heights for the Nano to explore. Once the set is built, each daredevil Nano bug can bravely scurry up the curvy spiral ramp where it will connect to the zip line with the help of its custom-fit “backpack”, and soar down to the lower-level cul-de-sac where it preps to do it all over again. In addition to serving as the perfect starter kit for first time Nano owners, this set makes a great connecting piece that can bridge the gap between any other existing habitat sets, enabling children to customize and create the ultimate playground for their HEXBUG Nano to traverse. The HEXBUG Nano Zip Line Starter Set includes 23 easy-connect pieces and one extremely rare Nano mutation with removable zip line backpack. Launch date: 2012.
