I love this little guy. Dumbo octopuses are fantastic demon creatures.  If I lived 4 miles underwater in perpetual darkness, I would certainly choose a spot to plant my Plexiglas bubble home where they hang out at.  Nothing too big, a modest 30ft in diameter perhaps, 3 stories, open floors,  some house plants, bedroom on top, a freezer full of flash frozen fruits and vegetables, state-of-the-art electrolysis water to oxygen generator. I would imagine it would be cold as balls in the abyss, so a smart heating system. An exercise bike so I can charge the deep cell batteries to have electricity, iPad bubble craft navigation app.  If I had Branson money I would make it happen. This is so bananas I might have to knock that place down and put my shop there.
