Octopuses are intelligent, in that they can solve mazes, and open medicine bottles, and have better memories than many of us, and yet they have shorter lifespans than mice. And that's just a small fraction of their weirdness. Moving eight legs individually, having independently functioning suckers, near human eyes, no bones or shells, and the ability to travel short distances over land... The weirdness continues. And so they are creatures that haunt our psychic story land. Unlike unicorns and dragons, these monsters are real, and beautiful, and ugly, and so very fascinating.
And taste good. Especially in okonomiyaki.
Imagine your hands were octopuses, typing emails to friends.
