While Dr. Smith has the Robot do his chores for him, he suddenly becomes hypnotized by a strange humming sound and wanders away. He walks straight into a transparent cage and the door shuts behind him, trapping him inside. Will runs to help him, but a creature arrives and the boy must flee for his own safety. The monster pounds on Smith's cage; Smith comes out of his trance and screams in terror when he sees the creature. A noble-looking man appears and points his glowing staff at the monster. The monster quiets and walks into another cage nearby. Then both the man and the monster vanish.
