One day, Knersus wakes up with a funny feeling. He's totally lost his will to chase Oscar and decides to retire. Oscar isn't happy with this new development. Who will chase him when he gets bored? He asks Wonderwoef to help him provoke Knersus into chasing again, but nothing works. Finally they pretend to have stolen Knersus' spare teeth. This makes the pterodactyl so angry that he sets off after the rabbit without delay
