Well, in the 'big mom is luffy's mom fanfic', they might have crafted a story where Big Mom is Luffy's mom. But it goes against what we know from the official 'One Piece' story. Fanfictions like this can be really interesting as they can rewrite the story in unexpected ways. They might have some interesting plot twists and explanations within the fanfic to justify this relationship, but it's not part of the main 'One Piece' universe.
As a result, he had 29 children, 20 of whom were born during his imprisonment. However, the search results provided did not provide any information about the specific outcome of his descendants. Therefore, I don't know the exact outcome of the eldest brother's descendants.

Big fruits and youtiao were different foods. Although they tasted similar, their shapes and names were different. Big Fruit was the name used in the northeast region, while Youtiao was a common name used all over the country. In addition, there were other names in different regions. For example, Tianjin called youtiao as guozi, some areas in Henan called it oil fruit, Guangzhou and surrounding areas called it fried ghost, etc. Therefore, although the big fruit and youtiao were similar in taste, they were different in shape and name.
Well, big fruit cartoons often have vibrant visuals and creative storylines. They might focus on teaching kids some basic values or just be pure fantasy for enjoyment. The characters usually have distinct personalities that kids can easily relate to.
I'm not sure specifically about Raven's mom story in Big Brother 17. Maybe it was about her family background, her influence on Raven's life, or some specific events related to her that were mentioned during the show.
One key event is her rise to become one of the Four Emperors. Another is her many battles to expand her territory. Also, the events related to her family, like the marriages she arranges for her children to strengthen her alliances.
