Karl heads of to Africa to go meet a Gorilla. Before he travels to Uganda, Karl agreed to start in South Africa as he's been there on holiday he heard it was alright. Ricky and Steve want Karl to have an authentic African experience so they arrange some time in a slum with a family and helping a charity rebuild a shelter. Karl visits Jessica the Hippo who lives with a family and Ricky sends him to join a Rhino conservation project before heading off traveling through the impenetrable forest in Uganda before coming ‘face to face' with a Gorilla.

Karl's last "thing to do" is seeing Japan's most spiritual destination: Mount Fuji. On arrival in Japan Karl gets lost in Tokyo. Ricky and Steve put him up in a ‘capsule' hotel, send him to a Sumo wrestling stable, arrange for Karl to meet a Zen Master and send him on the world's steepest rollercoaster. And he has to attempt to climb Mount Fuji.
