I was watching the followers video yet again, taking note of the beautifully painted scenery, and I noticed a little frog like demon sneaking up behind the barbarian. This is the first time I’ve seen this creature in D3, but no one else on the Battle.Net forums seems to have noted it (or at least cared to note it in all the follower controversy). Maybe its been around for a while and I just didn’t notice it earlier?
It appears at 1:14 in the video:
Here are some screen shots I took of it:
