There’s a stone, a tree, another tree, and a coat rack. That stone and two trees will make the perfect foundation for a house to put that coat rack in! This stone is flat and heavy and both of the trees are flexible and durable.
After you finish the foundation, the only step that's left is to wash the entire thing with soap (そ).
