The second part of the credits, in which, after wild animals and fights as were expected, you can see Tarzan's family, and particularly Jane and Kala looking moved.
The freeing of the Leopard men from La's slavery/control in "The Leopard Men Rebellion" was surprisingly heartwarming when one gets over the initial shock of the episodes twist ending.
After Edgar Rice Burroughs himself has been hearing about all of Tarzan's amazing exploits, Jane comes to say that all those stunts are only one part of the man. In truth, he's a much kinder and gentler person that his power would have him appear. Coupled with flashbacks of their romance.
