Here's a party favor that really packs a punch! Our mini Rock'em Sock'em Robot packages include 2 red robot rings and 2 blue robot rings. To use, slip a robot ring on your middle finger facing outwards and then press down the head until it clicks into place. To play, use both pointer fingers to make the robot punch his arms up and down. Face another player to start the battle. Whoever makes the other robot's head pop up first wins! This timeless toy is sure to knock your guests' socks off!
