Captain Murphy opens Sealab to tourists, eventually prompting Dr. Virjay to renounce his religion, and begin to eat meat from cows.

Kommissar Murphy brings Marxist-Leninist ideals to Sealab.

Hollywood Actor Beck Bristow (Brian Bloom) comes to Sealab to study for a television role.

Due to an incident with Chubby Carol, Quinn (who doesn't think Carol is so chubby) is blackmailed into giving each crew member a robot body, but what is to become of the crew's old bodies?

The Sealab crew attempts a daring rescue mission to Ice Station Zebra, one of whose inhabitants has turned to cannibalism. They are accompanied by a German who "came with the sub," bears more than a passing resemblance to Jürgen Prochnow and is given to firing his pistol inside the sub and shouting "Sieg Heil, Cornelius Drebbel!" Unfortunately, the two inhabitants of Ice Station Zebra cannot be rescued due to a lack of wetsuits, thanks to Debbie packing an attractive dress for herself instead.

Debbie and Quinn break up, while Dr. Virjay gets his old rock band back together.

As Captain Murphy leaves for The Great Spice Wars, a new captain, Tornado Shanks, is given the helm.

A delivering mishap and some dishonesty on Sparks' part pockets Sealab a brand new Asteroid Smasher/High-definition Television. Unfortunately, the ASHDTV was supposed to go to Spacelab so they could destroy an asteroid hurtling towards the earth.

Dr. Quinn teaches Debbie Love's class of 4th-graders including Fatass McBlobbicus, while having to deal with Tornado Shanks' warped and unscientific view of education. The classic story "The Scarlet Ibis," by James Hurst, is ripped off as part of a classroom discussion of death. All the while, cuts are made between Debbie Love's classroom and the spa Love is visiting, creating a series of double entendres.

Quinn, White Debbie, and "He Who Smokes Bitches" Stormy Waters venture deep into Tornado Shanks to destroy a malignant tumor in Captain Shanks' head.

Tornado Shanks declares Sealab a sovereign nation in order to be his own tax haven. A wave of secession fever sweeps through the entire crew, with a half-dozen nations declaring themselves independent in a few minutes; with the help of two British businessmen, they are all soon armed with missiles allegedly loaded with nuclear warheads. When push comes to shove and every Sealab nation declares war on every other one, however, the nukes all turn out to be duds.

Stormy's meddlesome inquisitiveness uncovers Shanks' membership in a world-controlling society.
