The small buckle fell to the ground and down the green pipe. The buckle was supposed to hold the saddle to the horse and so this caused the rider to fall off and fall to the ground. Meanwhile, the buckle floated along the pipe and clean water swam behind it pushing it along.
The rider could not afford a new saddle so she needed to get the buckle removed from the drain pipe immediately before it was pushed any further and was lost forever. Panicking, the rider stuck her hand into the narrow pipe and carefully pulled the buckle out.
