The schoolyard rules are changing, and surviving means getting tough. According to the classic playground rhyme, first graders are babies, second graders are cats, third graders are angels, and fourth graders are rats. Now that Suds is officially in fourth grade, his best friend Joey insists it is time to stop being a nice kid. Fourth grade rats are supposed to be fearless. They say no to their mothers, push little kids off the swings, and absolutely never cry. Suds desperately wants to fit in and play the part, but every time he tries to act mean, something feels terribly wrong. Will Suds learn to toughen up and embrace the rat life, or will he discover that you do not have to be a bully to grow up? Enjoy a fast-paced, funny story about peer pressure, friendship, and staying true to yourself.
