Beardie making odd puffing sound?

[Heroicchip]

Maybe I’m being a lil paranoid.. maybe not, but this is concerning me. My beardie will “puff” at me and it sounds like a little compressed breathe of air. He will do this multiple times a day sometimes multiple times in a row. I just got him a couple days ago and he’s been doing it since. Is he just scared or being territorial? I just gave him a bath and i have a video of it here https://youtu.be/svsoPNlgOWE please help me identify this i would very much appreciate it. Also another video of it here https://youtu.be/UYZBUruY_2g

Hi there, I replied to this in the other E.R and the general forum. He's just new so give him time to settle in.
