Isabelle and the Tooth Fairy

So, Isabelle lost her tooth the other day, and every morning she would wake up and the tooth fairy had forgotten.  When the tooth fairy finally remembered, this is what she found:

 We thought maybe Sarah was in collusion with Isabelle to get the tooth fairy to clean her room, but it was just because she loved Sarah, and wanted something nice to happen for her.  Sweet sister.  However, I think she was disappointed in the response of the tooth fairy, that things disappear when a fairy tries to clean a human's room-- something about fairy dust not working on human chores.  The tooth fairy also said that magic happens when a human child cleans her room, and it makes the child's mother really happy that they did all on their own.

She cleaned her room really well the next day.
