Yeah Yeah Beebiss I is a rumored lost game for the NES that was first mentioned in the June 1989 listing for mail-order video game service, Play It Again, where it would reappear until September before being removed from the listing and then show up on another mail-order video game service known as Funco. There's no known information about the game other than it's title, however there are various theories to the game, from it being a mistranslation of a Japanese game, with the most popular theory for this one being the game Rai Rai Kyonshis: Baby Kyonshi no Amida Daibouken, to the game being a copyright trap made up to spot other magazines who were copying them. As of 2022, none of them have been confirmed.
