Between 1997 and 2000 there were these beanbag plush toys called Meanies which were Meant to be parodies of Beanie Babies. You can easily google them if you want to learn more. Anyways there was a Meanies Club I was a member of that would send out newsletters alerting of new Meanies or other Meanies related news. One time they mentioned a Meanies Cartoon coming to Fox Kids. This must've been in the Spring of 1999. It didn't say when it would be coming but there were two pieces of character art of Splats The Roadkill Kat and Donnie Didn't Duck. A bird which had it's head cut off. I assume it would have had humor similar to Ren and Stimpy or Rocko's Modern Life since that's what the toys were like.
Speaking of Meanies. There also an un produced Meanie which was meant to be part of the Infamous Meanies line which were based on current trends such as a parody of Furby or Pikachu or Celebrities such as Dennis Rodman who was renamed Dennis Rodmantis or Bill Clinton which was renamed Bull Clinton they were portrayed as anthropomorphic animals. There going to be an OJ Simpson version which was a gorilla dressed in a football jersey with a butcher knife named OJ Chimpson but obviously they realized this could be perceived as racist and decided to cancel it. No images of it exist online.
