Ricky's suggestion of the next bucket list item to do - meeting the endangered mountain gorilla in its natural habitat - does impress Karl, if only because of their likeness to humans (Ricky states they are 98% genetically identical to humans). Although the gorillas Karl will meet are located in Uganda, Stephen and Ricky think Karl should see other parts of the sub-Saharan African continent while he's there anyway. They first send him to South Africa to help with a charity advising local children and rebuilding huts, which ends up unnerving him primarily because he requires a security guard on his stay. While Karl's there, Stephen and Ricky encourage him to partake in an activity which he didn't do on a previous trip. Karl then drives to a residence, the owners who have a hippo as a pet that has access to the inside of the house. Next, he visits with the Ndebele tribe, where he will learn their painting techniques, while he cooks a meal for their king. He is next sent to take part is a major wildlife conservation project where a wild male rhino is being relocated for the survival of the local females. Finally arriving in Uganda, Karl is first tasked with purchasing second-hand clothes to wear for his gorilla meeting, the actual meeting which is not quite as Karl expects, but which he still takes away profound realizations of life.
