Ten years ago while searching for Hidden Mickey's in Africa, I asked a Cast Member if they knew any in the area. What happened next led to an eye opening realization that Disney characters are hidden everywhere. She explained to me that one day while having an opening meeting in the seating area for Tamu Tamu Refreshments she was staring at the wall and discovered their was a character there.

Just after entering the seating area from the main section of Harambe head to the far right wall. Just next to the exit here you can find none other than Baloo carved into the wall!
