It (probably) works just like the Podium of Vigour, which means that only creatures with idle animations should be animated. An easy way to know if the creature will be animated or not is to simply find one and stand next to it. You'll see the same thing in the podium as you see in game when it isn't moving. Getting a list of all such creatures is possible but a considerable amount of work, which I'm not willing to do now (hence a comment, not an answer).
