Tooth Fairy for the nonverbal child?

I was so worried about how my 6 year old would react to his tooth becoming loose, I never gave a thought as to explaining the Tooth Fairy. This was for my eldest boy, so whatever we do, we have to get him excited to leave his teeth so his brothers will buy in to the idea of the Tooth Fairy when their time comes. I always have on hand some little animal figurines in case I need to redirect a meltdown. I thought I'd tie a bow around the animal and leave it next to our Tooth Fairy box, a small wooden box with a secret door, but how will he make the connection it's from the tooth fairy?
Daddy came up with the idea of wrapping it, to give him the pleasure of tearing paper(something often done, but usually it's my catalogues or a letter from the post), and then putting a sticker or tag of a tooth on it. What a great idea!
I went online to find a photo when I saw a photo of one of the Tooth Fairy's helpers from Rise of the Guardians. He likes the movie a lot, so maybe I should use that. This helper fairy is holding a tooth and carries a coin to leave behind. I printed up two photos to use as tags, business cards are the perfect size for something like this, one for the recent tooth and one for the very loose tooth next to it that will probably fall out tomorrow. I wrote his name on the tag and attached it to the gift. I also put a coin in the box since it is his first tooth. He doesn't care much about the coins, so I will get more figurines to wrap up and tag from the Tooth Fairy.
He loved it. He was so excited to see the tag with his name on it from the Tooth Fairy, that he hadn't opened the package. We opened our secret wooden box and saw the tooth was gone but a coin was left behind. His other teeth won't be replaced by a coin in the future, just the gift. I only needed it to show the younger boys what will happen when they lose a tooth. :)
