Introduction to the toad watching the sky: The toad is lying on the hillside at an angle of 15 degrees. The stripes on the front are very similar to the head of a toad. There are rocks protruding from the top, like frog eyes; there is a crack like a mouth on the bottom. Look up to the sky. The lower part is white and the upper part is black, which matches the physiological characteristics of a toad. The whole thing looks like a toad squatting on a hillside.
