I agree, Boomer has that same look in his eye that Taz did. But at least he stayed put. Taz would have high-tailed it out of the same room.
It's funny because the little ones have no fear. The elders, if you will, get all pissy and hissy, growly at them and they don't even seem phased by it at all. They go back for more! (At least this is how Paizly is.) Is Sooner that same way?

I also love how Sooner is stretched out in the first pic. Almost like he's testing how close to Boomer he can get.
