The old toilet in the bathroom at the back of the class never acted up before. But this year its flushing itself and making strange noises. The janitor says its because of all the digging contruction workers did over the summer to build the new school wing. Danny thinks thats probably right-but he wonders if all that digging disturbed somthing else besides the plumbing. When his friend Megan catch that on video, Danny dosent get it. Why would a ghost haunt a toilet?
