Who watches the watchman? You don’t have to worry so much as usual about the answer to that question when the watchman is a Friendly Shark. Someone told me once that in Japan a character carrying a lantern on a pole is a watchman in a graveyard, so maybe this is Thresher is a spooky comic. (Maybe for Halloween, if I can come up with a story.)
Regardless, I seem to be getting better at drawing a pajama shark standing up. The relationship between the fins and the tail is a delicate one.
The lanterns are simply two of the first three types that came up in a Google image search for “lantern”.
