Bjarne Betjent sings a ballad, in the first season Episode 28, based on the book Den blå planet (The blue planet) that he got from Blekkulf. While Bjarne sings, illustrations from the book are shown. (illustrations by Vivian Zahl-Olsen)
The song is about the blue planet that humans share with animals and plants, and that we all should look after it.
