George is bored with all of his bath toys so he brings some new ones into the tub with him. What he doesn't realize is that not all toys float, and he causes a clog. Bill and the Man with the Yellow Hat are excited for their big hike. Bill is looking forward to collecting leaves and the Man wants to do nature drawings for his art class. George doesn't find any of these activities to be very exciting and longs to see some real action.
