Underpants of the Sea: Harpy's fight for a clean sea

Down in the ocean not far from land

a pair of old undies lies in the sand

And the undies, believe it or not,

are used by a couple of friends as a hut

The sea urchin Harpy and the sea snail Gregg

both found a home, one in each leg

One day Harpy has had enough ... but is it possible to find a home on the ocean floor that feels, looks and smells better than those horrible underpants? Let’s find out!
