Not to sound too negative, but I kind of feel like the timing of this story is suspect. It seems to be on the heels of numerous articles [1][2][3] from Pixar talking about their new character, which is an octopus, escaping and rescuing Dory the fish.
FWIW, I am a huge fan of cephalopods and have a large octopus tattoo enshrining my admiration for the animal. They certainly are highly intelligent, so the story isn't impossible.
But the story doesn't even mention Pixar or Finding Dory? Is this some sort of new ultra low-frequency subliminal advertising? Or are you just being a little paranoid? You're the one who brought it up, maybe you're the one working for Pixar.
