On March 16th of 2019, a Twitter user by the name of Trader Hoes mentioned that on Nickelodeon one day, they played Jimmy Neutron Boy Genius and there were ad spots that featured the Yolkians, likely King Goobot and Ooblar and other Yolkians talking directly to the viewers about the movie. It is unknown whether they exist or not. https://mobile.twitter.com/Biptisms/status/1106973417176293376
