When he later comes home from shopping, he sees the vacuum cleaner and toaster destroyed, then suddenly feels a tremor from another room. He opens the door to his basement and tries to turn on the lights to no effect when he sees his robot staring angrily before pulling out his blow dryer and cutting the cord with a knife. Aquarius is terrified as the robot approaches him.
During the fortune message, Aquarius is running away as the robot chases him.
