Freddy Monnickendam is a businessman and executive producer of the animated television series The Smurfs (1981), Snorks (1984), and Foofur (1986).
This led to the fast deterioration of relations between the two men, ending in court cases about the division of the rights and the money involved.
Annoyed by these discussions and problems, he decided to start a new series of cartoons called Snorks, which were created and designed by Nicolas Broca.
[3][4] Having bypassed Dupuis, the collaboration between the publisher and Monnickendam ended, and as a result, SEPP International S.A. was disbanded.
Monnickendam continued to work with Hanna-Barbera on such shows as Foofur (created by Phil Mendez), The Completely Mental Misadventures of Ed Grimley (based on the Martin Short character), and other shows (including Tom and Jerry Kids), but he was never able to replicate the success he had with The Smurfs.
