Operation: S.P.I.N.I.C.H. / M.E.S.S.A.G.E.

S6 E5: "Operation: S.P.I.N.A.C.H." (Salad Pushing Invaders Now Attempt Crusade Here) The shores of Gallagher Elementary are invaded by the Spinach Armada who are on a crusade to make kids everywhere enjoy spinach. The KND are not about to let their fellow students be tortured into spinach eaters, but does one of them actually enjoy spinach enough to help the invading Conquichetadors?! / "Operation: M.E.S.S.A.G.E." (Make Express Shipment Speedily Avoiding Gummy Enemies) The Kids Next Door run a Pony Express-like note passing service at Gallagher Elementary boasting that not a single note they've delivered has been read in front of the class. When Numbuh Two (in full cowboy persona) is given the task of delivering an important note it seems that everyone in school, including the Six Gum Gang and a tribe of wild kindergarteners, are out to stop him!
