Three Wheel Tracks is the second level of Coaster Valley in LittleBigPlanet PS Vita. Regular old parts are useful enough, but Otis needs some rarer kit from The Scrapyard to finish his cannon. Fortunately Sackboy will be travelling there in style with the Triangular Troublemaker: a three-wheeled buggy that can drive on walls and ceilings!
After the stage's first falling debris hazard there is a segment with a spinning wheel on which the Troublemaker must ride upside-down. The seemingly empty area above this obstacle contains the key to the Toy Tanks side level.
