This is how the cephalopod takeover begins: Not with a bang, but with a seashell slowly rolling along the sand of a wet beach.
Below, we find beachgoers examining a closed seashell that contains some mass inside it. They pry it open to find out that it’s a small squiddy-octopus type creature, and man, is this thing upset at being discovered.
These humans shriek with a nervous glee while our invertebrate friend seemingly puts its dukes up, ready to dole out harm like Squiddly Diddly on a bender. The whole encounter ends with the camera person running away after his friend throws the octopus at him.
