Codename: Kids Next Door Operation S.P.I.N.A.C.H./Operation M.E.S.S.A.G.E. (2002–2008) watch online HD

In "Operation: S.P.I.N.A.C.H. (Salad Pushing Invaders Now Attempt Crusade Here)", the Spinach Armada arrives at Gallagher Elementary. These invaders have been sent from a foreign land on a mission to force kids to eat spinach. The Kids Next Door, of course, refuse to let them succeed, but it appears one operative actually likes spinach and might not be so willing to help his teammates. In "Operation: M.E.S.S.A.G.E. (Make Express Shipment Speedily Avoiding Gummy Enemies)", Numbuh 2 is given an important message to be delivered through the Kids Next Door's Baloney Express note passing service. That won't be so easy with the Six Gum Gang and a tribe of wild kindergarteners after him!

The Spinach Inquisition is a parody of the Spanish Inquisition song

Originally, Tom Warburton wanted Mel Brooks to be in this episode to sing the Spinach Inquisition song as a tribute to History of the World: Part I. But was unavailable due to some schedule problems.
