Fly is fed up with everyone studying butterflies. After all, flies go through metamorphosis too--and they are so much cooler! They flap their wings 200 times a second, compared to a butterfly's measly five to twelve times. Their babies--maggots--are much cuter than caterpillars (obviously). And when they eat solid food, they even throw up on it to turn it into a liquid. Who wouldn't want to study an insect like that?.
