On March 4, 2017, Kricfalusi announced a second new studio to be based in Miami, Florida, named John K. Studios. The studio's only project was an animated short for Adult Swim, advertising the then-upcoming UFC 200 match on July 9, 2016, produced prior to the announcement of forming the company. The short was referred to as the "big project" in Del Valle's previous announcement. As of July 2018, the studio website is offline. The possibility of any further successor companies to Spümcø is uncertain due to the sexual harassment allegations against Kricfalusi in 2018. In 2013, a website was created to promote a documentary about the Spümcø animation studio. A teaser trailer was posted on Vimeo which included brief interviews with Kricfalusi, Spümcø staffer Eddie Fitzgerald and self-proclaimed Spümcø fan and singer-songwriter "Weird Al" Yankovic, and clips from "Ren & Stimpy" and other former Spümcø series, giving the impression that it was authorized by Kricfalusi. However, sometime in 2014 or 2015 the website was taken down and the Vimeo account was deleted without notice or explanation. Many of Kricfalusi's fans were left wondering if the people involved in the project were unable to get further funding or a distribution agreement or that they could not obtain the proper licensing to use clips. On February 1, 2013, "Sick Little Monkeys: The Unauthorized Ren and Stimpy Story" was published by animation historian Thad Komorowski. The book contains the detailed history of Spümcø and the "Ren & Stimpy" cartoons.
