You're the builder and operator of this huge "steel" style modern roller coaster replica from K'NEX. The world's smallest real roller coaster, the Screamin' Serpent has 23' of fast twists, hairpin turns and gravity-defying loops. It also features realistic coaster sounds and a clanking, motorized chain lift. Rider figures that press into the seats and cars are included. Follow the instructions to build the full-size, 3 ft.- high coaster. Or, put together the smaller version, the Screamin' Serpent Junior, for a wild ride that sends riders zooming through a series of canopies. 1,283-pc. kit. Uses 2 AA and 3 AAA batteries (not included). Ages 9 and up. Made in USA.
