Extend your imagination by expanding your FleXtreme Spidey circuit! This refill of 72 tracks, i.e. 1.72m additional tracks, will enable you to imagine and build an even bigger circuit! 2 spiderweb- ... shaped suction pads are also included, so you can hang the tracks on various smooth surfaces. You can then continue the crazy race: climbs, descents, upside down passages, spins, loops!
