The Grain

I sit by the sea
Made of rocks and dust
Under the sea
From one to a thousand
Yellow black or grey
I sit there all night and day
With my friends it will stay
All around the bay
Across our faces walks a crab
Pinch, pinch it will stab
I am beaten up
Then I hear a yap and along comes a pup
He comes around and flicks me away
Picks up a ball ready to play
But he cannot stay
The tide comes up
Washing engraved
Footprints away.
