This snake is trying to hold onto the mouse box - when exploring, snakes will often coil around things to help them stay secure. It’s just a snake thing. The box is too light to use as an anchor point, though, so it’s moving with their body and the snake is a bit confused about that. All’s cute here, though - nothing but relaxed and curious body language from this snake (note the relaxed muscles, steady movement, and alert but not worried tongue flicks).
Also hilarious that it’s a box for a computer mouse, leaving us with a delightful visual pun.
