Why did the green cover of the hillock slowly vanish?
The green cover of the hillock slowly vanished because all the animals who came to visit the sick stag started eating the tender, juicy grass on the hillock.
Word spread about the delicious grass, and soon there was not much grass left for the old stag to eat.
