The Paper Bag Princess is another fun book by Robert Munsch. It is fairy tale-ish, with familiar characters...and a big twist!
"Princess Elizabeth was a beautiful princess." She was going to marry perfect Prince Ronald.
A dragon destroyed the castle, prince-napped Ronald, and burned off Princess Elizabeth's clothes! There was only one thing not burned by the dragon - a paper bag. Princess Elizabeth put it on and followed the dragon in order to save the prince.
The dragon loved to breathe fire and was a little too self confident. Elizabeth tricks him so she can rescue Prince Ronald.
When Princess Elizabeth rescues the prince, instead of being happy, he tells her she's filthy! The not so prince-ly prince tells her to come back when she's dressed like a real princess.
