"Power Lunch" has similarities the "Fantastic Four" superheroes from the Marvel Universe. In this case, the Gangrene Gang are given powers that bear striking resemblance to that of the Fantastic Four - Big Billy becomes a giant rock (the Thing), Ace gets ice powers + flight (the reverse of the Human Torch), Snake becomes super stretchy (Mr. Fantastic), Arturo gains super speed and Grubber has powerful burps.
While raiding the snack shop, one of the chip boxes that Arturo opens looks very much like a Pringles box, having even a face with a mustache on it.
