Michael Jackson left behind three children the world knew little about when he died more than four years ago. "Remembering Michael" is a new documentary that now sheds light on intimate details about the King of Pop's personal life through the eyes of his children.

"It took me until I was, like, six years old, to learn that his name was Michael Jackson. He was always 'daddy' to me," Jackson's oldest son, Prince, 16, says in the documentary.

Jackson's youngest child, 11-year-old Blanket, also speaks publicly for the first time about his future aspirations.

"I'm going to try to help, like Africa, because that's a very poor continent," Blanket says. "There's a lot of animals that are being killed from, like, poachers and stuff. So, I want to help, like, endangered species of animals."

Paris, 15, describes the great lengths her father went to protect the children's privacy. Their secluded upbringing included wearing veils and masks in public.

"We didn't know a lot of kids, like, our age," she says. "We were more secluded. We never really left the ranch that often."

The documentary, executive produced by family matriarch Katherine Jackson, can be viewed on Fundanything.com by fans who pay a $10 fee online. Contributions are being solicited online at different levels in exchange for memorabilia to cover licensing costs.

"[Katherine] really wanted to fund this without asking any of the people around her, including the Michael Jackson estate, for funding," Kirk Schenck, producer of "Remembering Michael," told ABC News.

The children believe, sometimes, that Jackson's eccentric lifestyle and behavior were misunderstood. "It's not right to invade someone's privacy like that," Blanket says.

In one scene from the preview, Prince talks about how his father pushed the children to be great. "He wanted us to always … be greater at it than anybody else had ever been," Prince said.

Jackson, 50, died in 2009 from acute propofol and benzodiazepine intoxication.

"He promised me he would teach me how to moonwalk," Paris says. "He never got around to it."
