The Civic-minded Five are introduced in this episode.
The Civic-Minded Five are: 4-Legged Man (team leader), Capt. Mucilage, The Carpeted Man, Jungle Janet and Feral Boy. (In the Tick comics, the Five are Feral Boy, Fernslinger, Oddman, Mr. Envelope and team leader Radio King.)
4-Legged Man may be a parody of the X-Men character Forearm from the Mutant Liberation Front, who has 4 arms, as opposed to 4-Legged Man, who has 4 legs.
