There's a giant sitting on a huge toilet in a tree. He's crapping all day and this is causing a huge poop surplus in your country. You and your tip up truck are going to do something about this. Load the poop into your dump body and drive to the coast, where you dump it all into the sea. Don't drop anything off your truck, otherwise it will become an even bigger muck than it already was!
