Dr. Bushwell is an animal researcher who lives in Africa in her animal refuge for chimps. Every day, she gets up at 5:30 am and watches the chimps. She then eats roots and water for lunch and watches the chimps some more. At night, she thinks about chimps until it is time for bed. She was exposed as a fraud by Greenpeace as she was using the chimps in her refuge to run a diamond mine. While they raided her home, they found diamonds everywhere (even on the soles of her shoes). Her research was revealed to be nothing but pictures of monkeys from famous movies (including, the apes from Planet of the Apes, the flying monkeys from The Wizard of Oz, and King Kong from King Kong) She had become insane from being lonely and greedy. She is likely still in her refuge and running her diamond mine.
When the Simpsons were lost in Africa, they found a chimp that led them to Dr. Bushwell's refuge, where they stayed until they could call for help. During that time, some potential poachers invaded the refuge to take the chimps, but it was revealed that they were actually members of Greenpeace coming to rescue the chimps. They reveal that Dr. Bushwell is using the chimps as slaves to run her own diamond mine. Dr. Bushwell admitted that she had snapped due to crushing loneliness and greed. When told they would get help for her, Dr. Bushwell fearfully bribed the Simpsons with diamonds, claiming that "Diamonds will make everything all better". The Simpsons (except Lisa) accepted her offer, thinking she was a "nice lady".
