I'm pretty sure that's a clove cigarette. No, I have no idea how that works underwater...probably by the same mechanism that's keeping his little beret on...
Another little pencil piece on brown paper--this one's about 6 x 7ish.
Original is for sale...uh... $45? And I could even do prints of it for $10 plus shipping--visit Red Wombat Studio to order [link]
