This third episode introduces us to Phuak's new band, the Phuak Five, while Pexky brings her pet alligator to meet the other terrified contestants. However, it is Pingpong's surprise that nearly breaks several contestants. The hosts are stricter than contestants anticipate, prompting one of them to be punished and another rule breaker to be given a card.

In episode four, Pexky's pet alligator comes back to bite a contestant, just as a chaotic wedding brings unexpected laughter. Dr. Tum orders a detox for one very constipated contestant, and a special show challenges contestants not to joke, revealing a foul in the next episode.
