When Sophie is flipping through the TV channels, she stops at an Sinterklaas-themed episode of the series Flodder (1993), which was based on a movie of the same name. Dick Maas created the movie, its two sequels and the series that was derived from it. Johnny Flodder was played in the first two movies by Huub Stapel, the same actor who plays Niklas in 'Sint'. Johnny Flodder in the series footage, however, is the late Coen van Vrijberghe de Coningh.
