The Tooth Fairy

The Tooth Fairy is an occasionally mythical figure who leaves money for young children in exchange for their outgrown teeth.

The Tooth Fairy meets Maria in episode 3060 of Sesame Street, and proves who he is by showing how much he knows about Maria -- she used to live on the Grand Concourse of the Bronx, and he would leave a nickel under her pillow whenever she lost a baby tooth. Right now, he has a problem: he doesn't know which of his two unmarked bags is full of teeth, and which one is full of money. He's not willing to look inside them, so Maria suggests that he shake them to see which bag is which. She remarks to the viewer, "This is a very unusual street."

Later in the episode, the Tooth Fairy is distressed because he's just been "ambushed" by a grinning bunch, which means to him that his money will soon be gone; he'll be "cleaned out" by said gang tonight. Maria offers to call the police, but he says it won't work. Suddenly, he spots "them" - the gang he mentioned, which consists of kids with missing teeth! "A very unusual street!" exclaims Maria.
