I thought I'd add to this thread as I saw the video below, posted by Brian at Riverside Reptiles, one of my favorite places to go.
I do have a friend who lucked out and has a "nice" VBB, but apparently, that's not exactly the norm. This doesn't look like fun to me, but to each his/her own. They are stunning and great feeders. Also interesting as they like to climb a lot and at the exhibit at Riverside, they are usually up in the branches, like the green mambas he has. Of course, the green mambas scare me more.
