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 (by Vivian Zahl-Olsen) appear from the book.
The song is about the blue planet that humans share with animals and plants, and that we all should look after it.
