Tin fish

Was surfing the ocean blue
Hanging ten, that's five times two
Went out too far and it was a struggle
To get back to the shore

Still out too far and it got dark
I sensed a shark, but it was not
That's when i saw the jagged teeth
Of a subversive submarine

Tin fish swimming underneath
I hope it does not feed on me
What does it want? what does it need?
Please swim, swim, swim away!

Somehow made it back to the shore
Was badly bruised by the coral floor
That's when i looked out into the distance to see
The tin fish laughing at me

Tin fish swimming underneath
It chose not to feed on me
What did it want? what did it need?
Such a submissive submarine
