When Robotnik built his luxury resort, Club Robotnik, he planned to flood Scrap Valley to make it into Robotnik Lagoon. He sent a giant crab compactor which devoured all the robots' houses. After sabotaging Club Robotnik, Sonic and the rejected robots destroyed the entire resort. The robots then used the scrap metal from the destroyed resort to rebuild their home. Robot eventually came to live in Scrap Valley after running away from Robotnik and Scratch and Grounder.
