Snaptrap has a secret plan to share with Bird Brain and the Chameleon, not shared by DOOM: selling an expensive mansion that is not legal for sale and scare guests and keep your money. Meanwhile, T.U.F.F. agents see that the aforementioned mansion is for sale, and sells his owner (actually he is against selling, but all that was a plan of Snaptrap, Bird Brain and the chameleon, which is discussed below), the TUFF agents buy the mansion. They arrive at the mansion, and the chameleon becomes the owner of the mansion and the mansion sells a very expensive price (with the money they earned during the events of Snaptrap's Mom).
