"You deserted us, frog princess. It ain't nice to desert your friends."
"There are no friends in Cobra, Buzzer. Only convenient alliances. We're all cannon fodder when it suits Cobra Commander. (*coughing*) I... I learned that... the hard way."
- --Buzzer and Mara discuss inter-office relationships.
"What can I say? I'm attracted to morons."
"And I have a thing for mermaids."
- --Mara and Shipwreck, flirting in a most curious manner.
Animation and technical errors
- While the sailor aboard the Nerka reports to Commander Jordan that the Cobra submarine is making its escape, Mara's troubled breathing, from the previous scene, can still be heard.
- Were all the JOE underwater specialists busy that day? How else do you explain Alpine, the Joe mountain climber, leading an underwater diving mission?
- Why is is that Cobra always insists on putting the Joes through slow-moving, easily escapable traps when a single bullet to the head would suffice? Here, Lady Jaye is placed on a slow-moving gurney in order to put her through the same machine that transformed Mara. Like clockwork, Mara sees her and recuses her moments before it's too late.
- This story continues in "There's No Place Like Springfield."
- Genetically modified underwater specialists is a concept that Cobra would seemingly perfect years later with their Hydro-Vipers.
- Mindbender's project that Iceberg was caught up in in Iceberg Goes South would be another example.
- Cobra and M.A.R.S. are able to exceed the technology levels of G.I. Joe since they ignore legal restrictions and are not subjected to treaty inspections.
- Mara joined Cobra to escape poverty. Many other Cobra agents join for the same reasons.
- Shipwreck is an expert seaman, yet knows little about diving.
- In the "Now you know..." attached to this episode, Gung-Ho explains that you shouldn't judge people until you give them a chance.
Real world references

- The distinctive sound effect used for the TIE Fighters in Star Wars is recycled here for the Cobra Firebat in flight.
