for EllRay Jakes Walks the Plank! by Sally Warner and Jamie Harper
Things are going just swimmingly for EllRay. He's finally getting along with most of the kids at school. He's even getting along with his family. But then everything comes screeching to a halt when his younger sister accidently overfeeds the classroom goldfish EllRay was supposed to be taking care of over Spring vacation. What is EllRay going to tell his teacher and the kids in his third-grade class? Fortunately, most of them are sympathetic. But not bossy Cynthia. She sees this as an opportunity to blame EllRay for her own mess-ups. Must EllRay now walk the plank for stuff that he didn't do?
