Whoosh! Don't get caught by the Dragon! The K’NEX dragon's revenge roller coaster building set lets your creative builder make a real working roller coaster with a burning castle and motorized 'flying' Dragon. The set includes over 650 parts with amazing theming and K’NEX rods and connectors that snap together with a satisfying “click”, plus a coaster car and track. A motorized chain lift sends the coaster car screaming through twists and turns, past the ferocious Dragon, through the burning castle and back to safety. Perfect for builders ages 7 and up, K’NEX supports key areas of a child’s developmental growth, like fine motor skills, manual dexterity, and spatial awareness, putting them on a path towards greater understanding of stem subjects. But they won't know that they're learning; they'll be having too much fun building their own mini working roller coaster! Easy-to-follow instructions are included for a frustration-free building experience.
