The tooth fairy did remembered to takes Will's note/tooth last night. But what she didn't remember was that there was a $5 bill inside the folded up $1 bill she left him. So imagine Will's surprise when he woke up in the morning and found she had left him $6! Now I have to explain that I don't think the tooth fairy meant to leave that much and he should not expect $6 each time he looses a tooth. Since he has 3 other loose teeth it shouldn't be too long before he learns that the tooth fairy usually only leaves $1.
