However, Captain Murphy grabs Sparks as he is being electrocuted, killing Sparks as well.

The Policy

A mysterious Asian visitor brings an irresistibly cute Gloop (reminiscent of shmoos) onto the station, which Murphy names Squishface.

There is also a reference to the popular fps shooter Return to Castle Wolfenstien when Debbie calls out "I need ammo!" and a bullet icon appears over her head.

Fusebox

A loophole in the Sealab charter turns everyone into captains, except Stormy (too stupid), Quinn (too proud to exploit the loophole), and the Chinese crew members (because of previous Asian accomplishments, including anime, among other things).

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.

Frozen Dinner

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

As it turns out Sealab was built on an ancient Indian burial ground and is now sinking into the ocean floor. The only hope to save Sealab is John Bear, Sealab's resident Native American.

The cast looks back over five years of "A Legacy of Laughter" in the style of one of those tacky TV reunion specials but of course since this IS Sealab, not all goes well.

Legacy of Laughter

The year is 2021. Deep below the ocean's surface, looms a vast, magnificently high-tech compound: Sealab. A multi-national scientific station with an annual budget in the trillions, manned by a motley collection of malcontents and screw-ups who were unfit for work in the private sector. They really don't get any research done, but instead spend their time bickering among themselves or just plain goofing off. The crew have manipulated their luckless leader, Captain Murphy, into submission, and are content to ride the government clock, raking in fat, hazardous-duty paychecks.
