Dead goldfish + bossy girls = big trouble!

Things are going just swimmingly for EllRay. He's 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 Zippy, the classroom goldfish that EllRay was taking care of over spring vacation. Zippy is a goner. What is EllRay going to tell 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 Ell- Ray for her own mess-ups. Must EllRay now walk the plank for stuff that he didn't do?
