John Kenn Mortensen was born in Denmark in 1978. He is a writer and producer of television shows for children. The father of a pair of young twins, he finds he has very little time to do anything much, but when he does have a spare second, he draws pictures of monsters on post-it notes.

What I do know is that John's monsters absolutely hit the spot
