Tooth Fairy Friend and she comes with a tag saying:

This is so exciting 
You have a wiggly tooth!
I'm here to keep it safe and sound
When it eventually comes loose
I will keep it in my pocket
I hope that you don't mind
This way it will be easier
For the Tooth Fairy to find!
Once it's been collected
And a treat is left for you
I will stay and be your friend
Always steadfast and true!
