Blizzard, like they did the snake model, has updated the frog model as they said they would, and while it's not in the current build, Mumper posted a picture of it, which I assume is from an internal build they are currently testing.
This was posted on Twitter by Mumper, but I found it on Scrolls of Lore, therefore, credit to Insane Guy of Doom on the ScrollsofLore forums for bringing it to my attention.
