This story takes place in Africa, so no iguanas. There are crocodiles, but they play no truly important part of the story. Crocodiles are much more prominant in the Tarzan movies. Well, here goes.
Jungle: good, good, good. Crocodiles: good. Apes: Don't care. Man dominating nature: bad. Overall Rating: Two mustard greens and a kale. (Marginally recommended for iguanas.)
