Nano V2 bugs can climb up vertically, horizontally, around corners, through loops and tubes, to the tip top of any Nano V2 habitat set. The HEXBUG Nano V2 Gravity Loop set features an evolved Nano, sporting a new look, with 3 rubber spines on its back, as well as a new system of tubular tracks that highlight the Nano V2's unique multi-level climbing abilities. Uses the physics of vibration to scurry up through multiple levels of tubes, as high as the V2 set will take it. Each Nano V2 is capable of crawling through tubes on its feet or on its back and can pass another bug in a single tube to avoid a traffic jam. It can even flip to its feet when landing on its back on an open flat surface. Comes with 1 Nano V2, and 18 piece
