If you go down in the sea today, you're sure for a big surprise.
If you go down in the sea today, you'd better go in disguise,
for every slug that ever there was, will gather here for certain because
today's the day the nudibranchs have their picnic!

It's amazing the picture ideas that stem from a single status quote...

The quote I used was read off of a friend of mine's skype--

And this was born after I looked up what a nudibranch was again... (Wow, all those biology classes reallllly paid off didn't they *snerk*)

Only other thing I can say is that the text involved in picture is a nod to Gary Larson, who I think probably would have used sea slugs in one of the Far Side panels if he were still cartooning.
