A Special Shell

Pink and cream, a shining shell,
purple stripes coil around it
as smooth as an orb and as bright as the silvery moon,
I listen to the shell and I hear it whispering its story.
Pounding waves and bubbling water,
rolling and churning and splashing.
I hear a gigantic sea trapped inside a tiny shell.
As the shell finishes telling its story,
I realise it is a special shell.
