Also known as Spooky Floating Bunny Head, Nailbunny was Johnny's first and last pet, a rabbit whom he fed once and then nailed to a wall. Only the preserved head (which was torn from the body by Mr. Eff) remains by the end of the comic, the rest of the body apparently unnecessary for the afterlife. It is unclear whether the disembodied head of Nailbunny was actually given the ability to levitate by the supernatural force that permeates Nny's house, or that Johnny is simply hallucinating during his interactions with the dead rabbit. Among the group of Johnny's "voices," Nailbunny appears to represent Nny's conscience and "voice of reason," a role he on occasion expresses exasperation with. He is responsible for persuading Johnny not to kill himself, and also acts as a conversation partner during some of Nny's more introspective moments regarding his life and killing sprees. After Johnny dies and is subsequently returned to the newly rebooted universe, Nailbunny no longer appears, although on at least one occasion it is suggested that Nny still hears his voice. Based on the mascots for a certain company (Pillsbury) that produces muffins, "Psycho-Doughboy" (aka "D-Boy") and "Mr. Eff" are carved foam figures that were once part of a pastry display. After being taken home and repainted by Johnny, they were given personalities through supernatural means, and throughout the story appear to represent opposing "sides" of Nny's insanity. Later on, it is also revealed that the two are affiliated with the monster behind Johnny's blood-painted wall: D-Boy refers to the creature as his "Master" and expresses a wish to be reabsorbed into this master, while Mr. Eff seems to have relinquished his devotion to it, and would prefer to become a "real" entity in his own right. In his role as one of Johnny's "headvoices," Mr. Eff appears to represent Nny's more manic, homicidal side, as he encourages Nny to kill remorselessly to obtain blood to repaint the wall. However, this action also has a selfish motive, since as long as the monster remains inside the wall, it will feed more power to Mr. Eff and Psycho-Doughboy, making them more real. Psycho-Doughboy, on the other hand, represents the depressed, self-loathing aspect of Nny's insanity, encourages Nny to kill himself on several occasions.
