Should I really be happy?

Something was pinching my nose. I opened my eyes and there was water and sand everywhere. A crab pinched my nose and my pain receptors became active all of a sudden. It hurts.

I threw the crab away and looked around. Behind me were endless waves of water and in front of me was a jungle of coconuts.

"What about the old man!?"

There was no sign of him. But something else was missing too. It was also quite obvious.

Damn it! The sword is gone! Actually, everything was gone apart from my underwear and some cloth around it. They were still here thanks to my belt.

The sun was in the west and it was evident that the night would visit soon. Some part of my pants was still attached and my underwear peaked from within. It was kind of embarrassing but at least I had survived. Where is this place?
