Description: A yellow rubber duck with a wide, gaping mouth on its belly, creeping around the sewers on four bug legs. Luna thinks it's cute, but I doubt anyone else thinks so too. It belches fire for a short ranged attack.
Strategy: Watch for it to stop moving, draw back, and shiver a bit, as this is your signal that it's about to attack. The flame attack actually has much shorter range than it looks; you have to be standing almost right in its face to get hit.
