The Mysterious Island

You decide to swim to the island. A floating ring on your backside isn't helping much and makes you task very difficult. You slowly make your way to the island. Finally after a long time floating and being hit by coastal waves, you reach (smash violently into) a beach.

The impact manages to dislodge the flotation device from your rear and sends you flying into a coconut tree. You somersault out of the way of a falling coconut and you realise that you are on a small sandy island that is part of a larger two island archipelago.
