Since I don't know the exact content of 'jim the farm boy part 3', I can only guess. Maybe it continues the adventures of Jim on the farm. He could be dealing with a new crop season, perhaps facing some difficulties with pests or bad weather. Or it might be about his relationship with a new character on the farm, like a neighboring farmer or a new farmhand.
It might start with the farm boy having a reason to send something to the Filipino. Maybe he made a friend during some kind of international exchange program on the farm, and he wants to send a local product as a gift.
Once there was a boy on a farm. He had a simple life. Every day he would wake up to the sound of the rooster crowing. He would then go out to the fields to help his grandfather plow the land. He learned how to plant seeds and take care of the young plants. He loved watching the crops grow over time. When the harvest season came, he was overjoyed to see the fruits of their labor. He would load the carts with the harvested produce and take them to the market in the nearby town.
Sure. Once there was a boy on a farm. He woke up early every morning to help his father feed the animals. There were cute little chicks, gentle cows and frisky horses.
