Awesome! I suspect cephalopods are a lot more clever than we think they are. This video (which is in German, so I have no idea what it says) shows another octopus who likes coconuts. It gets especially fabulous just past the half-way mark.
In that article, it mentions that octopuses are known for making mischief in aquariums. My son has gone to a couple summer camps at Sea World San Diego where they get to go to the restricted parts of the aquariums to meet the animals. They met an octopus who would extend a tentacle out of his tank, moving the lid from tank next door, which contained crabs. He’d reach down into their tank to crab some poor unsuspecting crab, which he would then bring back to his tank to consume. It had taken Mr. Octopus a little while to figure out how to do it, but once he had, crab feast every night, at least until the staff caught on.
