Unique model, unusual build — “Somewhere between classic space and futuron, this robot is an odd but special set. Almost the whole torso consists of the 9V battery box that is orientated vertically, and every other element in the build has to adjust to this, resulting in very unusual SNOT techniques for... More such an early model.”

“Bulky robot designed around the battery box with two deployable hover chairs. Red and blue astronauts. One light and a sound brick that emits two space sounds. 9V lights & sounds! I find it curious that the robot comes with two sets of hands: grabber jaws or shovel scoops.... More The hover chairs are cute.”
