I had a children's book called (I think) The Magic Gourds. It was based on a Korean folk tale about two brothers, one good (Hungbu) and one evil /greedy (Nolbu). The evil Nolbu tricks the good Hungbu out of the family inheritance.
Hungbu and his wife and children are good but poor. Hungbu helps an injured bird, who reward him by bringing him a gourd. They plant the seeds, and out of the gourds that grow come riches and fine clothes and they grow wealthy.
Nolbu hears of this and in his greed, injures a bird only to help it. The bird brings him a different gourd. He and his family plant the seeds, but this time out of the gourds that grow come nasty critters that hurt them and destroy their riches. They realise the error of their ways and everyone lives happy ever after...
