Shark Tooth Necklace

This is a tooth,
But it's not my tooth,
It's a shark tooth,
It's not just a tooth you see,
It's a world inside my amazing tooth,
It's a tooth land filled with wonder,
It has magic with great blue seas,
Outside the world there's a tooth,
As pointy as can be,
It's not just a tooth you see,
But that you know,
It's more precious than a world,
It is a world you see,
More powerful and special,
Then the great blue see,
This was a powerful gift that keeps me safe,
And as lucky as can be,
This was a gift to me from the king of the sea.
