We discover Catbug’s origins in “The Dimension Garden,” set 10 years before the present day, when Beth finds a baby larva in her dad’s garden. Wallow soon grows attached to the creature and falls asleep with the larva in his arms, only to wake up stuck the outside of a massive cocoon that has filled his room. Catbug emerges from the cocoon fully formed with superlative cute non sequiturs for which this character is known. In “Hamster Priest”, new sides of Catbug’s personality are presented through Catbugs from alternate dimensions, in which he takes on the persona of “Commander Catbug” and “Lord Catbug”.
