Sunna is wagging her tail?

Ok so today I took all three of my baby beardies outside for a while (one at a time of course), to let them get some nice warm sunlight.

When i got to my smallest beardie, Sunna, she started doing something strange. She would run around a little bit (which is normal for all three of my beardies) but when she sat still, the end of her tail started wagging! Not the entire time, but just at random moments. If I had had my phone with me I would have gotten a video.
It wasn't even her entire tail, just the last half of it. It wagged like a snake slithers, side to side.
I've heard of beardie behaviors and not once have I ever heard of a beardie wagging their tail. This is the first time I've seen a bearded dragon do that.

So I guess my question is, has anyone ever seen something like this before? Is there maybe a reason for it?

My Nim did that before he ate a cockatiel fluff. I saw my leopard geckos do it all the time. That was the first and only time I saw my Nim do it. I believe it means attack is immanent. Maybe she saw her shadow or a bug? It is the cutest thing ever.

Maybe XD I had just put down a small plate of veggies for her, so maybe she was wagging because of that... Ill see if I can get a video of it (if she does it again that is) next time I take her outside
