Enemies immune to Greater Command

[Daliena]

As per title, noticing a bunch of enemies being immune to it with little explanation from what I can gather so far. Wolves in Ravenloft content, hyenas in Chamber of Rahmat.. I certainly don't see a Protection from/Magic Circle Against Evil on them either. So what exactly is immune to GCommand?

(P.S. Please fix Gianthold already, after several necro characters I'm getting mighty miffed about the cloud giants being immune to Necrotic Ray.)

D'oh. Where's a druid to cast a spell to let you speak with animals when you need one?
