Go on a brand new adventure with Boomerang Mario as he enters a spooky Ghost House! Featuring K'NEX's all new jump disk and launcher that allow Mario to run and jump, like he does in the game. Build Boomerang Mario and open the doors to enter the Ghost House. Use the jump launcher just inside to collect the hanging coins! Look out for the Boos - you can spin them using the red gear on the back! Use the appearing platforms to travel up to the second level, then use the sliding platforms to get past another scary Boo! Once you reach the top level, grab the Star Medal, but bewar! Big Boo is spinning down a rod to get you! Jump down before he hits you, pop-up the goal flag and you've cleared the course. Combine your Ghost House building set with the rest of the K'NEX Super Mario™ building set line to take Mario on an even BIGGER adventure! For ages 8+.
