A tropical island

I went ashore early
It was dawn
Walked up a hill
That was impossible green
And snakes
I man sliced open a coconut
I drank its sweet
Fulfilling nectar
I saw the ship old as a *****
Misused by too many
I had nowhere to run
This was an island
Walked down the hill
The sea was crystal clear
Fins of sharks
Perfection had to wait
A man sells coconuts
By the wayside and
A green hill that is
Poisonous
And has too many snakes.
