Pollution! All around! Sometimes up! And sometimes...down! But always...around!
Drake, LP, and Gosalyn go to the beach, but oh shit, there's litter. This was from when we had that crazy-ass fad of caring whether we destroy the entire earth, so it evinces concern about these things--though it makes the common error of conflating mere littering with more heavy-duty pollution. In any case, Drake is completely blasé about all this, which seems odd, but Gosalyn's all for wreaking bloody vengeance on the perpetrators. Literally: "Sorry, dad, but you can't use kid gloves on these polluters; you gotta fight to draw blood!" Good words to live by; I just wish we had some people in congress who thought that way.
Anyway, to cut a long story short, there's a sardonic, diminutive fish-woman named Neputunia who commands aquatic life and wants to fuck our shit up by flooding St. Canard. She's an appealing character, and it is to be mourned that apparently she only appears here and in the two-parter, though I suppose given her very specific situation, there's only so much you can do with her. She does end up flooding the city, and it's actually kind of bizarre; it's apparently deserted, as we see no indication that anyone's panicking or trying to escape or anything.
Yadda yadda, the day is saved, as Launchpad convinces her with very little effort that flooding the city is bad and stuff because good people live there too. Hard to see this as being much of a solution, though, since there's no indication the pollution won't nonetheless continue.
-"Next time I get a day off, we're spending it in a library!" 'Day off,' eh? The plot thickens.
-"Danger, Launchpad, is my middle name!" "Yeah? Oh, funny, us being in a situation like this and me just now finding out what your middle name is!"
