Each Swap-A-Roos set contains five 1" (2.5 cm) to 2" (5.1 cm) tall soft vinyl figures that are great just as they are, but we find that it's much more entertaining to swap their heads and bodies to create strange new species like the Frogbot, the Robolion and the Toucoon. All of the heads work on every figure in each set. Illustrated blistercard with spinning wheel on the back that shows all the combinations. UPC
