This theme reminds me words from an ancient Chinese poem... 

Walking in Busch Gardens, Heard a strange noise... "gee wheeee... gee wheeee... ", I went to take a close look... aha!... discovered two giant turtles (tortoise) were making love. The male one (on the top) were humping the female one, the female one seemed unconcerned... chewing a bud of flower she had just found near by.
The strange noise I heard was the sound of their heavy and thick shells grating each other.

That afternoon, every animal was sleeping, it was very quiet, the Sunshine was warm and pleased. A good day for a nap and having a sweet dream.
