The power goes out, and everyone's wondering what happened. Ed starts a panic when he blames the blackout on "mole mutants" (a parody of the C.H.U.D.s and The Mole People), and Eddy tries to cash in. Meanwhile, Rolf enlists Kevin in jump-starting the power grid, and Edd overcomes his fear of the unsanitary sewers to conduct his own investigation.

After Eddy reads "Eddy is a no neck chump" on the wall, he goes undercover as "Carl" to find out who wrote that. While he's with the kids, he is surprised that they actually treat him with respect. Eddy decides to ditch Ed and Edd and hang with the other kids, but Edd is determined to get him back.
