But it was too hard for them to cut down the trees. So they gave up the idea and decide to build a hay cabbin. However, as they found the hay, they considered it too soft to build a house,so they gave up again. Several hours gone,they thought of another kinds of materials ,such as stone ,sand and even leaf, but all of them didn't come true .At last, they had gone back home with nothing finished.
