It quickly became my favorite thing in DAK. (Of course, that will be temporary, as the novelty gradually wears off.) It's just marvelously done, and worth spending 30 minutes or so watching. In between the actual vignettes, you'll occasionally see a little movement here or there. On one occasion I recall, quite a large movement.
The showings aren't in order, but random, so you might see one more than once and another not at all. (Somehow I've seen the one with the fox about half the time.) And they aren't on a schedule - sometimes as close as 5-6 minutes apart, sometimes longer.
One of them is actually centered around Disney movies with nature themes, rather than focusing in a particular animal on the tree.
