How to design an ocean themed room? - how to make designs with shag bands

My friend is 16 years old and she loves all the fish and the sea. I wonder how all the elements put into a room and did not see age. It has also opened blue walls, soft carpet orange circle and a yellow, orange, pink and green bean bag. Any idea or advice?
