[Nice try, but these Moblins do not react to "distractions", just like Zelda does not react to your dialogue. He should notice though that they follow a specific pattern and speed while walking. There will be points where one is on the opposite side of the hedge and the other has its back turned, giving them a clear shot at getting to the other side. Will he recognize these windows of opportunity?]
The Moblins may be tall and strong, but they do not pay very good attention to their surroundings. If we wait until their backs are turned, we might be able to run past them.
[There's your clue. Now, it will be a miracle if you can get Zelda moving fast enough. Good luck.]
