Third in the series of K'Nex amusement park rides, the Octopus Whirl is a 454-piece set that builds an expansive 2’-wide thrill ride.  Swiveling seats dangle from the long spokes, attached to the center carousel, which spins on an included motor for a realistic model.  Children can build an entire carnival with the other three Amusement Park models. The motor requires two AA batteries; not included.
