History[ edit ] Creatures with tentacles appeared in Japanese erotica long before animated pornography. Among the most famous of the early instances is an illustration from the Hokusai Katsushika novel Kinoe no komatsu popularly known as The Dream of the Fisherman's Wife. It is an example of shunga Japanese erotic woodblock art and has been reworked by a number of artists. They would have recognized the print as depicting the legend of the female abalone diver Tamatori. In the story, Tamatori steals a jewel from the Dragon King. During her escape, the Dragon King and his sea-life minions including octopodes pursue her.
