My name is Marvin and  my little lighthouse guides ships where to go, standing firm on a rock when icy winds blow.  I climb up the stairway trying to reach the top, winding higher and higher then suddenly stop.  Looking out the window, blue waters are           sparkling bright, dreaming I jump in and swim, I shut my eyes really tight!  LET’S SEE, LET’S SEE, WHAT CAN I BE?
