*grins* Yes, I'd have to say The Black Stallion would be my favorite animal related movie as well! Such a magnificent movie, there hardly is no speaking done (well except when they get back to civilazation) but yet there is so much emotion conveyed.

As for song... hmm... I don't really know, the only one I can think of right now would be "The Last Unicorn" but I dunno if that would be classified as an animal or mythical creature *shrugs* (great movie too tho).
