The park's name comes from two of Studio 100's shows: "Samson and Gert" and "Kabouter Plop" ("Dwarf Plop" in English). So take "Plop" from "Kabouter Plop", "sa" from "Samson and Gert" and add "land" - you get: "Plopsaland".
When the park operated under the "Meli Park" name it was themed around bees. The park had it's own bee hives and sold honey and honey products. "Studio 100" and VTM ("Vlaamse Televisie Maatschappij" Dutch for "Flemish Television Company", "Flemish" being the language of northern Belgium) bought the park after the 1999 season and has themed the park based on it's various T.V. series.
Several scenes from the French movie 'Le sens de la famille' (French for 'The sense of family') were filmed at Plopsaland De Panne.
