Yeah Yeah Beebiss I is a purportedly lost NES game that was first referenced in the June 1989 catalog of the mail-order video game service Play It Again. It would resurface in listings until September before being taken down and later appearing in the catalog of another mail-order service called Funco. No further details about the game are known beyond its title, though several theories have emerged. One idea suggests it could be a mistranslation of a Japanese title, with the most widely accepted candidate being Rai Rai Kyonshis: Baby Kyonshi no Amida Daibouken. Another theory proposes it was a copyright trap designed to catch other publications that were copying their content. As of 2022, none of these theories have been proven.
