You’re fighting a XXX Pr0n
This is a shellfish who has been sucked into the seamy underbelly of adult marine life entertainment. You find yourself hoping his trench coat stays closed.
He gets the jump on you. Or, y’know, the swim.
He starts to smack you with his fishtail, but you distract him with a fishy tale, then reach up and poke him right in his eye! His eyestalk does limp and he scurries away, embarrassed.
You search the grounds for grounds to suspect that the Plot Device is here, but can’t find anything.
¿Y ahora, que?
