pride of Umgluck", weighs in at 382 pounds. The toy first became available to retailers during the 1964 season. Marx produced the action set, virtually unchanged, for well over a decade, until the packaging and characters were updated for the 1977 sales season with a more overt outer-space theme to make it appeal more to buyers looking for space toys following the release of the movie blockbuster Star Wars. Versions The game was available in the United Kingdom during the 1970s, where it was sold under the name Raving Bonkers. The two robots were renamed, with the "Blue Bomber" becoming "Basher Bonker" and the "Red Rocker" becoming "Biffer Bonker". Marx Toys also released an updated version of Rock 'Em Sock 'Em Robots called Clash of the Cosmic Robots in 1977. It featured robots of a design more suitable for the Space Age. The redesign was inspired by the success of the film Star Wars, released that May. Instead of a red robot and a blue robot, Clash of the Cosmic Robots featured PROG-2, an orange robot with a head more like that of RoboCop, and V-STYX, a white robot with a long, protruding mouth (but no eyes). The boxing ring was molded in black to give the game a look reminiscent of outer space. Stickers and decals (for both the robots and the ring) were provided, following the same concept. For a period of time in the mid-1990s the blue robot was changed to a darker shade of blue and given the old PROG-2 head. The red robot was changed to a grey color (though the instructions referred to him as "silver"), but retained his classic head. There respective names were changed to "Bolt Crusher Bob" and "Gear Grinder Greg". As in Clash of the Cosmic Robots, stickers and decals were provided for additional design. Aside from the cosmetic changes, the game remained the same. There have been many variations of the toy, such as a Transformers version, in which the two robots are Optimus Prime and Megatron. In 2000, a remake of the classic version was developed by Mattel—at approximately half the size of the original model. In addition, an action figure line, a PlayStation game, electronic handhelds, a head-to-head plug and play and bobble head dolls have been recently introduced. The PlayStation game was Rock 'Em Sock 'Em Robots Arena, published by Mattel Interactive, and was developed by
