He is the creator of Ketelbinkie, one of the most popular Dutch comics after World War II, and of Pipo de Clown, the star of a television show that ran from 1958 to 1980 which Meuldijk produced, filmed, and for which he wrote the script.

[2] In the early days of Pipo de Clown, which was initially broadcast live on Wednesday afternoon, Meuldijk did everything himself, from writing the script and casting the supporting actors to designing the set and choosing locations; he even built and painted Pipo's travel trailer.

[3] Meuldijk also wrote screenplays for other television shows, including Mik & Mak and Koning Bolo, and scenes for the Dutch Sesame Street, but remained pigeonholed the rest of his life as the creator of Pipo.

At the time of filming he was 81 and could not direct the movie, but did spend a number of days on the set in Córdoba, Spain.

[4] He is praised for his imaginative use of language[3] and is credited with coining a number of expressions that via Pipo and other characters from the show made their way into daily usage.
