In addition to Walt, the horse, & the polar bear, there's also the kid that Locke Monster himself has been seeing. Any one with him can see the kid, but he refuses to talk about it.
Clearly, Smokey is not behind every apparition.
The polar bears were in the Hydra island zoo. It's never specifically said but the Others did say they were keeping Sawyer & Kate in the polar bear cages, so you can make the logical jump there. Theoretically you could say the same for all the other animals seen too, though you'd have to explain how they got from Hydra island to the main island (the bears could swim it, but the boars?).
Walt was just "special" so that's why we've seen him all over the place. I'm assuming his story will go unresolved (much like Libby's). You know, after the show is done, I'd love to see Darlton do a series of comics or something to answer any unanswered questions.
