Non-spider ball python wobbles when stressed?

[Bogertophis]

We got our first BP yesterday. An enchi lesser morph. I've noticed he wobbles just a bit too when he lifts his head up to look around. I was rather curious if that was just normal/he was tired/a little stressed from travel/etc... It's very mild, and doesn't seem to affect him, but I did notice it twice!

I can't speak for the morph being a factor, but young snakes don't have well-developed neck muscles yet, so don't assume it's a "wobble"...snakes aren't built to periscope very well, & young ones are just not strong enough to be good at it yet.
