Sylvester and the Magic Pebble

This is a book to convey family affection.
The donkey brother who loves collecting stones found a magic stone, but he accidentally turned himself into a stone, and his parents searched everywhere sadly
One day, the donkey father took the donkey mother to a picnic. The donkey mother was sitting on the rock that the donkey brother had become. The mother's warm temperature woke up the hibernating donkey brother, "I hope to change back to the original me!" Little donkey thought. In the blink of an eye, he really changed back.
After the Zui of the story, the relatives were reunited, but the magic stone was useless. After a gain and loss experience, the family understood that they did not need those magical things, precious things were around us, and they needed it more - that is love!
As the author said:
I think the turning of donkey brother into stone indicates the relationship between him and his parents.
The little donkey in that rock is a monster in armor, but when he realizes how much others love him, he can come back. It's natural for children to go home at the end.
