Hail, Squishface

A mysterious Asian visitor brings an irresistibly cute Gloop (reminiscent of shmoos) onto the station, which Murphy names Squishface. There are two problems, though: Gloops stink, and they multiply so fast that eventually Sealab is overrun with them. This episode parodies "The Trouble With Tribbles", Gremlins, and Aliens. 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.

Der Dieb

A series of unexplained thefts leads Murphy to declare "Martian law". In the ensuing madness, everyone ends up blaming Quinn for all the thefts.

Stimutacs

Sparks starts pushing a new, "mostly kelp" energy pill that proves to be highly addictive.

In the Closet

Due to a faulty door, the Sealab crew gets locked in a tool closet. A few black eyes result as they try to get out, but then they discover that a pack of unfed killer dogs are running around Sealab.
