Gopher Broke. The Eiffel Tower beomes the latest monument to vanish into the ground as Dr. Claw begins collecting the world's monuments. Gadget and the Gadgetinis investigate the tunnels leading from the tower and capture a teenage mutant ninja gopher (I'm kidding about the ninja part). Gadget figures the case is solved but Penny realises the gopher is young and that its even bigger mother will come looking for it.
