The bumpers features a traditional norwegian mythological character called the "Nisse", who is something of middle thing between a gnome and an elf. He lives on farms in rural Norway and watches over the livestock and people living there. If you don't feed him properly, he will start misbehaving. I think this character is local to Scandinavia, alghough most old cultures have some kind of "house spirit" that needs to be respected.
