I’m living in a sphere but I’m standing in as a straight line.
I’m writing with a hand of five fingers but my pen is too thin just as a cylinder.
I have a mouth with teeth and tongue, but I drink water in a hemispherical bowl.
I have a body with a structural shape but I lay on a rectangular bed.
I have a small eye, but with it I see all the big creatures.
What is this? A wonder for a wonder!
