Actually, I have to correct my earlier reply. Iirc the argument is that all conscious animals engage in physical play, not necessarily that all playful animals are conscious. On the other hand, Humphrey does say that all animals engaging in pure sensation-seeking type play are conscious, so that’s probably the sort of play he’d need to bring him around on octopuses.
