Grizzly boy
(Book)

One day Theo wakes up and decides he's a grizzly bear. He leaps out of bed, practices his growl . . . and his roar. . . and scratches his bottom on the bedpost. "Oh my! That's very convincing," his mother responds. When Theo finds a bowl of lettuce and berries for breakfast instead of his favorite Frosted Monster Bites cereal, he is still determined to have a day that's wild and free, but he finds it's more difficult than he expected, especially when you have a clever mother and still have to go to school where there are rules and more rules! After a challenging day as a grizzly boy at school, Theo learns you can follow the rules and still enjoy being wild and free! -- from Amazon.
