Gangster Jack's Goons are a group of mobster cats, who work for Gangster Jack, appearing in the movie Peter No-Tail In Americat. They appear in Peter's America dream, and seemingly satirize the Mafia and it's connections, as an ordinary policeman is also shown to be part of the gang. The gang's signature pledge of allegiance is a repeated chant of "G-J! G-J! G-J!" They make a brief appearance in Worst Hero And Villain War Ever.
