Nandembo Caverns is a set of twisting caverns deep below the Pride Lands.
Nandembo Caverns are a series of labyrinthine underground tunnels, large enough for a fully grown lion to traverse through. The grey caverns show signs of erosion, and several areas have caved in to the extent that even a honey badger would have trouble moving through them.
After Simba and Bunga wind up in a sinkhole, Bunga suggests travelling through the caverns via a small opening. As Simba and Bunga traverse through the dark tunnel, Simba soon starts to become frustrated at Bunga's random route choices, since no consideration is being taken on which ones he chooses. Simba's annoyance with the honey badger soon causes an argument to erupt between the pair. However, their disputation escalates so much that they wander off in different directions. Simba is relieved to be away from Bunga, and soon starts to realise that he is in fact going the right way. This also leads him to the conclusion that Bunga must be going the wrong way. He soon remembers that no matter how annoying he is, Bunga is still his subject, and starts to backtrack for the little honey badger.
Meanwhile, Bunga slowly starts to cool down, hoping that Simba would return for him. When he mistakes some rocks for being Simba, he states 'no worries', which reminds him of his uncle's favorite song, which he begins to sing. As he is singing Hakuna Matata, Simba starts to hear his echoes and sings along with him. The two soon find each other in a clearing, and Bunga is surprised that he knows it. Simba explains that he was raised by Timon and Pumbaa before he was, and that they used to sing it to him all the time when he was growing up. Bunga then realizes that it sort of meant that they were like brothers, to which Simba agrees with. As the two laugh softly, Simba laments on how Timon and Pumbaa could not be there to see them finally getting along.
Meanwhile, Kion and the Guard have entered the tunnels, even managing to get Timon and Pumbaa involved. The pair cry over their lost cubs, though Bunga and Simba soon hear their echoing cries. They race across the caverns, following the voices until they find the source. A large ravine separates them, however. Simba, with Bunga on his back, copies Bunga's earlier idea, by running and leaping across whilst the pair yell "zuka sama" together. Kion is shocked to see that his father is finally getting along with Bunga, and the Guard are equally shocked to see Bunga riding atop the king. Timon and Pumbaa are relieved to see their kids back safe and sound, though Timon scolds Pumbaa for worrying.
