As seen in Heavy Metal magazine, a special one-shot of everyone's favorite intestinal ghost. While visiting the city, Gutt Ghost runs into an old friend named Sensation BOOM. Sitting on a stoop and going through a box of comics, Sensation shows off some rare issues including ones featuring Gutt Ghost himself! Consumed by tales from his past in print, Gutt fails to realize a literal growing danger behind him in the form of a Yellow Button Red. What exactly is a Yellow Button Red? We'll tell you this much, they ain't pretty and they will eat just about anything for a laugh. Thankfully, Sensation is no stranger to the likes of the Yellow Button Red gang. Time to see Sensation BOOM!
