Yeah, I thought it would be a rare power-up that had a cutscene when you used it. Like in the trailer of the game.

It does work like that also. If you talk to the great fairy after you get the hookshot on one level the moon will be summoned to hit the boss. This is just a detail for one of the weapons that does a similar thing on a smaller scale. Not quite as cool, but it doesn't bother me.
