A while back a YouTube video was going around titled Octopus Intelligence Experiment Takes an Unexpected Turn. Someone put food in a baby bottle with a screw cap and a rubber nipple. There was a hole drilled in the bottle so that the octopus could reach in to taste the food, but it was not large enough for the food to come out or for the octopus to go in. The idea, I suppose, was that the octopus would figure out how to unscrew the cap.
The “unpexected turn” was that instead of unscrewing the cap, the octopus just ripped the entire nipple out of the bottle.
I have mentioned this before but it bears repeating: this outcome should not have been an unexpected turn:
