Sea cucumber
The sea cucumber has no heart, and likewise lacks a brain.
It therefore can enjoy no art, but likewise feels no pain.
It creeps along the ocean floor, just eating sand and dirt,
And though its life may be a bore, this creature feels no hurt.
It cares not for the pretty reefs or for the teeming fishes,
Stuck in a world without beliefs, perceptions, dreams or wishes.
It simply occupies the sea in constant semi-slumber.
How pleasant it must be to be a simple sea cucumber!
