Pigboy is a pig with several human traits who goes to Skool. He wears green suspenders with a pig on the front and a small hat. He is noteworthy for appearing in only one episode, in The Frycook What Came from All That Space; whe Zim referred to the other Skoolchildren as "pig-smellies", Dib yelled out, "Would a normal human call his own race pig-smellies? We're not pigs!". This hurt Pigboy's feelings; he ran to Zita for support, crying. Zita reprimanded Dib angrily, saying: "Watch what you say around Pigboy!" Then, with a loud sob, Pigboy ran to the window and jumped out; the wind swept him away, and he was never seen again. Pigboy played a very similar role to Old Kid from The Nightmare Begins and Sluggy from the unaired episode Day of Da Spookies!.
