A winged cow is flying in the air. What a strange thing! You’ve heard of flying pigs before, but cows? This is a new and strange thing indeed! Cows with wings! What a silly thing to imagine.
You want a thing to help you fly with the cow so you put on your flying boots (ぶつ). Your flying boots are a pretty strange thing in themselves, but they're the only way you can keep up.
