I am a seashell waiting for somebody to see me. I am shiny and curled up like a cinnamon roll. I��m rough and sandy. I swim with the sea and the sea with me. I am cold inside so if you touch me you��ll shiver and quiver. I swim around the sea with animals living inside of me. I��m joyful in the sea with fishes and sea creatures surrounding me. I like being a shell because people can hear the sea inside of me.
