Popping back

[ScalelessTime]

My milk's back pops when he twists and turns on my fingers. What do you think it might be?

probably just popping joints or some gas(in the belly). I've noticed these sounds in many young snakes.

I've noticed my Hondo do this occasionally, not often, I would go with what mikoh said.
