"The Emerald Duck"
"Did You Myth Me?"
Gadget comes home from the supermarket with food and bad news for Penny and Brain: The store was out of their usual brand Metro Dairy Farms, so they have to make do with more expensive dairy products from the mysterious New Foods Dairy (whose logo is sinister and slightly familiar-looking: a yellow-eyed, black cow's face against a red background). Conveniently enough, Gadget is ordered to Metro Dairy Farms to find out why the cows there have suddenly stopped producing milk. The inspector heads out to the country to investigate, but Claw has something to hide and sends out for separate M.A.D. agents to intercept him.
Meanwhile, Penny noses around a refrigerated New Foods Dairy truck and is trapped inside. Once the truck reaches its destination (the dairy itself), the little girl escapes and discovers the whole operation is run by Claw. A scan with her computer book locates a rotating satellite-type dish atop a silo that is sending a signal to cows at other dairies in the area that has somehow dried up their milk glands.
Up the road a piece, Gadget (with Brain's anonymous help) avoids the pitfalls from Claw's agents ― a phony cop who tries to run him off the road, an unlikely farmer who gives him wrong directions, an agent driving a thresher through a booby-trapped bridge, and an assassin dressed in drag ― and eventually makes his way to New Foods Dairy (thinking it's actually Metro Dairy Farms).
Busy with their own evil dairy farm chores, the M.A.D. agents let loose a relentlessly persistent and aggressive bull to finish off the inspector. Gadget gets tossed around a bit by the bull, but manages to avoid serious injury. From his computer console, Claw spots Penny by the sound wave dish and dispatches an agent to take her out ― but it is too late, as Penny has already disabled the dish and contacted Chief Quimby, who arrives just in time to arrest all of the M.A.D. agents (including the bull), who have become encased in cheese, thus putting an end to Claw's evil scheme.
The episode title is a play on the commandment “do unto others”.
