Inspired by one of my favourite songs in the Super Nintendo game Earth Defense Force (EDF - a side-scrolling spaceship shooter with brilliant music) with the title of the level and music track "Naval Battle", i just had to play with the words. You know me, i just HAD to, hehe.
Oddly, i don't like using the word "navel" instead of belly button, because the word reminds me more of "outties" and - no offense to those with outties - they just offend my sensibilities for some reason. I don't like looking at them, they disturb me. But that's just my own brain's automatic reaction. I don't go around rallying against them or people who have them, i just avoid looking if one is present. Apologies again.
But i had to use it for this image, haha. This is on a piece of cardboard about a foot by a foot and a 3rd.
