The K'NEX SCREAMIN' SERPENT Roller Coaster set lets you build an awesome replica of today's "steel-style" coaster, and then bring it to life! Assemble the coaster track complete with twists, turns, and loops, pop the six thrill-seeking kid figures into the serpent car, and turn on the motor! Watch the cars and listen to the "click , click, click, as they climb to the top of the lift, plunge screaming down the hill, then head back up for another thrill-packed ride. Over 6 feet long, 3 feet wide, and 3' ft tall! It's building fun for the whole family!
