How to make a pink room look beachy

I'm 12 turning 13 and I'm really into the beach I live just metres away from the beach I have 1 big pink wall 1 medium pink wall and 1 small pink wall which is where the window is. I then have 1 big white wall and 1 small white wall. I can't paint it sucks since pink seems to not be a beachy colour I also have a greyish-blue carpet which I also can't change. All my furniture is white and I have a sand coloured desk! Can someone plzz help me with ideas to make my room beachy answers ASAP possibly by saturday coz I'm going shopping on Saturday to get stuff for my bedroom thx.

Just make some decorations from things you collect on the beach. A few conch shells, an old piece of drift wood, a chain of clam shells, a coil of old rope. If you can find photos of gulls, lighthouses or maybe a poster from a steamship or ferry that would add to the "beachy" look.
