Life as a Rock

Imagine if you will. You spend thousands of years on the bottom of the ocean. Then one day some kelp seed comes to visit you and decides it likes your company. An attachment forms. You watch the kelp grow and the attachment grows stronger each passing day. Then one day the currents and the kelp's grasp outweighs your mass and lifts you from your longtime resting spot in the deep. You are suddenly thrust upon a world of sand, sun and air.
In all the anxiety and fears you finally realize, "It is about time I took a vacation".

It is not uncommon to find rocks bigger than bowling balls washed up on the beach in this manner.
