a clowntheatre-piece for the whole family (children recommendation 5+)

It’s a story about a lighthouse guard, living on a small island, surrounded by friendly fish and cheeky seagulls. His mission is to guard the bright light.
He loves his lighthouse, together they master storm and wheather. But sometimes he feels lonely. He longs for a dear friend.
One day a bottle post catches his attention. Is there somebody waiting far out at sea?
