Question: Why is The Hoggett's granddaughter a spoiled brat and grandson very quiet?
Question: After Babe first tries to herd sheep on the farm, Rex talks to Fly and mentions that the two of them are ancestors of someone. Could this mean that he and Fly are related and have been inbred? When the puppies are for sale earlier in the movie, the sign for them says that Rex is a champion; it seems like a farmer would be careful not to inbreed a champion dog.
Question: What's the deal with The Hoggett's children and grandchildren?
Answer: Very vague question. There is no "deal" with them. They are just modern.
Answer: Personality traits of brothers and sisters are not necessarily the same, even if the parents provide a stable environment for their children to grow up. The grandson could just easily been the spoiled brat of the family. In the context of the movie, one of the grandkids had to be the spoiled brat to carry the story along and show the love of the grand parents for them, even if one of them did not appreciate the hand made doll house he built for her.
