Will, Penny, Dr. Smith and the Robot work to put together a time capsule that they bury during the night. On their way back to the Jupiter 2, they encounter a werewolf. The Robot blasts it and it leaves. They all run back to the spaceship and tell Don and John and Maureen what they saw, but no one believes them. John says if Smith wants to prove that there is really a werewolf, he should catch it. Smith is frightened, but Will thinks it is a good idea.
