Question: After Sabor the leopard jumps on the net to kill baby Tarzan, it instead launches him up to Kala, who catches him by the diaper. Why does Kala move Tarzan up and down several times?
Answer: Kala, who was on the floor above the netting, was attempting to pull baby Tarzan up through the space around the pole, but it was too small for an infant to fit through. Kala instead pulled Tarzan by his diaper along the slit between the boards to the end of the floor where she could then reach over and pick him up.
Question: This ones a two timer: 1) Isn't it breaking the Disney tradition that no evidence of violence can be shown when Kala looks around the tree house and sees bloody paw prints? 2) The bloody paw prints lead to the dead bodies of Tarzan's parents, if Sabor killed them, wouldn't he have eaten them?
Answer: Disney does not have a policy against the evidence of violence, they do, however, try to keep it at a minimum. As for Sabor eating Tarzan's parents, there may have been something that scared him off, even if it was just another animal nearby.
Answer: Leopards are known to hunt for sport. And predators in general may store away kills for later.
Answer: From the picture of his parents. He knows where everything goes, and it's not too hard to work out how to put them on.
