A taste of his own medicine...Dennis Cookman is the  biggest bully at Sweet Valley Middle School. Elizabeth and Jessica  Wakefield, along with the whole sixth grade, are trying to figure out  what to do about him. When Dennis smashes Jimmy Underwood's bicycle,  some of the kids feel he's gone too far.Just because Dennis is  bigger and older doesn't give him the right to pick on the sixth  graders. Something has to be done to stop this bully once and for all!  That's when Ken Matthews comes up with the perfect dare that will  expose Dennis Cookman as the coward that he really is.
