Adult Dib made a cameo appearance in "Attack of the Saucer Morons", and has only appeared in one other episode: "Mysterious Mysteries". He only had one line throughout the series: In "Attack of the Saucer Morons", after having his head bitten down on by the pig, he said, "The pig accepts me!" He was seen again in "Mysterious Mysteries", communing with the Blotch with the rest of the Children of the Bright and Shining Saucer.
