Reading a list of facts about owning a pet octopus is simply a delight, and partially seems to be a list of things that you shoudn't do "unless you want to have some fun." Let the thing escape and leave unguarded fish bowls in the room? Yes please. Blue Ring Octopuses are incredibly lethal to humans? Sign me up. The fact that you have to keep them entertained by putting their food in puzzles seems like endless entertainment.
