Urechis unicinctus, a marine spoon worm also known as the fat innkeeper worm, or, if that doesn't sound delicious enough, the penis fish. And you don't even have to cook it! In China you might find them in a stir-fry, but in Korea, it's eaten raw. A little salt and sesame oil and you're good to go, a nice light meal after all that heavy holiday fare.
These guys have an interesting cuisine of their own. They secrete their own slime net to catch particles of food. And they're hospitable, hence the "innkeeper" name: they share the tunnels they dig with small fish and other marine animals, which also eat their leftovers.
All in all, a perfect symbolic animal for this holiday, right?
