The cornfield is where Peaceville's Sludgefest is held. It first appeared in Space Jammin', where Grojband riding a defective mower (sabotaged by Trina) accidentally mows a symbol into the field. The symbol coincidentally was used by The Orb Experience as a challenge to a battle of the bands, leading them to land and accept Grojband's challenge. Although Corey is reluctant at first, when band leader G'ORB insults the human race, Corey angrily accepts. G'ORB declares the battle is to be held at Sludgefest and threatens to destroy Earth if Grojband lost. Later the orbs abduct Kon in the field to extract information from him, possess the Newmans, and abduct Trina to steal her diary. While possessing the Newmans they perform the song Entry 4987: My Secret Fear and Junk, which was a direct extract read from Trina's diary. Grojband however easily defeat the orbs with their new song My Secret is Out. Accepting defeat the orbs retreat and take off in their UFO.
