Aim
You see an animal wearing a top hat and decide to aim at it. The top hat is a perfect, giant target you use to take down this animal.
It's much easier to aim for an animal wearing a top hat than one without.

Ready, steady, aim... fire! You throw a bar of soap (そ) at the animal. Yes, soap. You were sitting in your bathtub, washing and scrubbing, then the animal in the top hat caught your eye.
Your aim with the soap is perfect! The soap knocked the animal's hat right off.
