Grüner See – floresta submersa http://amanari.org.br/gruner-see/
At Sriracha Tiger Zoo in Thailand, a mother tiger lost her cubs due to premature labour, then became depressed. Her health declined and she was diagnosed with depression. Zoologists wrapped piglets up in tiger-print cloth, and presented them to the mother tiger, who took them in as her own. Her health is back on track.
Would love to find out where this is and trapeze into the ocean :)
