A long time ago, on a very hot summer, the news spread among the animals: The sun was getting married.

The birds in the sky, the animals on the ground, and the frogs in the pond are all happy for the sun and prepare to celebrate the great event.

"Don't be happy too early." said an old frog. "We should be sad now, not happy!"

"Why?" the birds, animals and other frogs asked in unison.

"Isn't it?" the old frog replied worriedly, "There is only one sun now, and sometimes it will dry up the water in our pond, threatening our safety. If the sun gives birth to more than ten suns in the future, Little sun, if their heat is combined, will we still have a good life?"
