Embark on a creepy carnival adventure with the Freaky Funhouse Roller Coaster Building Set, from K'NEX. The slingshot launcher sends the coaster car up the hill and spiraling through the track! This set comes with over 350 parts, primarily rods & connectors, to build a K'NEX thrill ride! And if you collect the Screaming Sideshow Coaster Building Set and Scary-Go-Round Ferris Wheel Building Set (sold separately), you can have a working amusement park right in your home! Recommended for builders ages 7+.
