Remember that K’Nex Mario and Luigi Starting Line race set? Well you can make the race even crazier by adding on this Mario Kart Wii: Mario vs The Goombas Building Set.
You get to build Mario in his battery-powered Kart along with a moving Goombas Obstacle, a Mushroom and Star and 6 pieces of buildable track. You can really build a crazy track with all of the sets they are releasing. It is getting as cool as the actual game.
This Goomba set is $26.95 from Amazon.
