"There are six people in a house.  Mariel, Noella, Dad, Mom, Alvin, and a mean witch.  Don't worry, she's nice.  She has a bendy arm.  Oh, we need feet."

(Note: Alvin is Mariel's imaginary brother.  She plays with him pretty much every single day. We've gotten used to him, and really he is quite nice.  Very quiet and clean.)
