Geedis
Let's move on to a mystery with a humorous component that also has a solution. It all began somewhat innocently in 2017, when comedian Nate Fernald shared a photo of a metal pin on Twitter that featured what appeared to be some sort of fantastical creature by the name of Geedis. He had purchased a few of them from an eBay vendor, but didn't know who Geedis was, so he asked the question online in the hopes that someone might recognize it from an old comic book or even a foreign TV program.
It turned out that neither the eBay seller nor the internet had ever heard of Geedis. As Fernald's post gained a lot of attention, someone added a little more detail. They offered a photo of a sticker sheet with six fantasy characters on it, Geedis being one of them. We at least knew where the odd tiny critter originated because the sheet was marked "The Land of Ta," but that brought up a new query: what was The Land of Ta? Was it an old children's book or a TV show?
The secret wasn't solved until the podcast Endless Thread two years later. Sam Petrucci, a cartoonist well known for creating some of the original graphics for G.I. Joe, created "The Land of Ta." He created "The Land of Ta," a very brief run of fantastical stickers, for the Dennison Manufacturing Company in 1981. Nevertheless, it was only ever available as stickers. Questions like who made the pins and why they only made Geedis pins are still unsolved.
