In the video of this event the octopus just splashes at the guy for trying to fuck with it.
I'm terrified of the day one actually becomes angry. Life as we know it will cease to exist as our new overlords force us into manual slave labour. Trash and debris, endless debris, being picked up with bare hands. The reminding tickle felt in our guts of the terrifying comfort of a tentacle at the missed soda bottle....
You've never heard of the blue ringed octopus? Every aussie kid is taught to fear those fuckers from an early age. They will shit up your day real quick. Of all the things that will kill you here they are probably very near the top. Tiny little things too.
