You may be right....perhaps this choice of image reveals some Freudian subcurrent.
More likely though I liked the idea of a venegeful monster rising to the surface to get even for all that frozen kalamari.
I should have added that I didn't draw the squid-I'm nowhere near that good an artist-it was from some images my daughter had got together for a school science project. All credit to the artist, whoever he/she was.
