Tin Fish

I 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 fagged 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
