When Gorgious tries to flood the bathroom, wasting water when he falls asleep in the bathtub, Candy opens the bathroom's door and soaks the aliens' entire house. Etno then has a brilliant idea to flood the entire house into an aquatic-like atmosphere to keep human tenants away forever. However, two hydrologists, Professor Coustel (whose surname is a pun on that of Jacques Cousteau) and his assistant Bernard move aboard the submarine to observe some of the rare aquatic species (including the aliens themselves, who transformed themselves into a seahorse, lobster, two-headed octopus, electric eel and piranha with the SMTV so they were able to breathe underwater).
Etno a une brillante idée : les humains ne savant pas respirer sous l'eau, pourquoi ne pas inonder toute la maison ?
