T-Rex Trick or Treats by Lois G. Grambling

It's Halloween night and T-Rex still hasn't decided what costume to wear. He wants to have the scariest costume of all of his friends. He thought about going as a ghost, a skeleton, or a witch, but when his friends came to get him they had used all of his costume ideas. As T-Rex tries to figure out what costume to wear his frown gets bigger and bigger, until it's so big that he scares himself when he looks in the mirror! So he goes out dressed as himself wearing a big scary frown and gets lots of treats. But when he starts to smile with his long, sharp, pointy teeth, people seem to be even more afraid of him. So the ultimate question is: Is T-Rex more scary when he frowns or smiles? The friends decide they will figure out that problem next year. This is a fun, not to scary, book that's wonderful for preschoolers. It's a great way to help them act out feelings and practice making different facial expressions. It's always been a highly popular book on my shelf.
