Ringo is Edd's pet cat. She is a small tabby cat with green eyes, gray fur and black stripes. Ringo is generally depicted as having a friendly demeanour and is very docile, especially around Edd.
Ringo is named after Ringo Starr, who was the drummer for the band The Beatles.
Ringo's first appearance was in Cats Sleep Anywhere, an animated version of the 1957 poem of the same name written by Eleanor Farjeon.
Ringo's second appearance was in Edd Again. She was sitting outside the glass doors in Edd's front room, waiting to be let in. She proceeded to follow Edd up the stairs and into his room, where she slept on a pile of Edd's clothes. She was dreaming about sitting outside in the cold until Edd opened the glass doors and let her in.
Ringo makes an appearance in The Snogre, she can be seen near one of Matt's snowmen.
Ringo appears again in part one of The End, where she is being held by Edd when Tord asked what happened to the chairs, and seen again twice in the montage, being held by Edd, as one of the space cats, and in the garbage disposal bay, again held by Edd, when Tord launches the group into space.
Ringo later appears in the final scene of part two of The End sitting on Edd's lap while the gang watches "Return of the Insane Zombie Pirates from Hell 5", having survived the destruction of the house by Tord's robot.
