Slam Witch was an enormous living sandwich summoned by Gramma Stuffum in Operation: F.O.O.D.F.I.T.E.. It along with a witch-hat-wearing Stuffum chased Sector V across the neighborhood from Gallagher Elementary School to the Sector V Treehouse, where Joaquin the hamster used a machine made by Numbuh 2 to grow to the size of the giant sandwich monster and eat it. Slam Witch's appearance was accompanied by a parody of the GWAR song "Gor-Gor", performed by GWAR themselves specifically for the Codename: Kids Next Door episode.
