There is a ship in the horizon. Captain commands the pirates to prepare an attack. The preparations fail because they can't load the cannon right. Uncontrolled firing starts fires everywhere and breaks the main mast in half. The approaching ship is revealed to be a friendly whale, who puts out the fires with it's spout.

Habhab thinks that the vessel needs to be in better shape and orders Vlad and Gunnar to do the maintenance work. The captain thinks they are too slow and decides to show them how it's done. Unfortunately he is not a handyman and they end up with more bruises and more damage to the ship. While they goof around, the ship is out of control and ends up on a reef.

Pollo is missing. Vlad is fishing and gets a shark. Gunnar begins to fillet the fish and Pollo flies out of sharks mouth. Gunnar wants to have the bird for dinner, but Habhab takes the parrot back on its place. Pollo is confused and starts squawking orders when the captain tries to do so. When they finally get the bird to shut up, it bursts out gas from the other end.

The ship runs into the thick fog. Crew bumps and blunders on the ship as they can't see anything. They make plans on how they can navigate. They tie a string on Pollo's leg and send him flying above the fog. Following the bird's advice they end up on a steep mountain and drop back into the water like a cork. Miraculously the ship surfaces with a deck full of herring.

Gunnar and Vlad get a great catch of fish. The fishnet gets torn and the crew starts to clean up the mess. The two seagulls Ritz and Hilton start throwing herring all over the deck when the crew is trying to clean it. Habhab orders seagulls to be shot down with a cannon but in the end the only thing they manage to do is wreck the ship and feed the seagulls.

There is a mysterious hole on the deck. While repairing it, the crew is locked under the deck by two seagulls. The only way out seems to be the hole above them. After their escape, they end up shooting more holes on the deck and being locked up under the deck again. The seagulls are entertained.
