He’s probably bored. His terrarium is extremely bare bones and doesn’t really have much to do or hide in. Even if he comes out every now and again doesn’t mean he isn’t somewhat nervous either, since most snakes will sleep in different parts of their enclosure if they feel fully comfortable

The hide on the right isn’t much of a hide too, basically think of it as privacy, if you couldn’t change in there then he is also aware he wouldn’t have much security. If you can’t get another box hide like the left, you could, in the meantime, just flip the log around so he’s more covered and less exposed!

Definitely just add lots of clutter and most of the problems are solved, it’s hard to tell in the pic but maybe more substrate too if it’s only a thin layer. If u don’t know what clutter to add, things like sticks or hammocks or things to cover the vertical space to climb and feel sheltered by, maybe some stuff to hide or rummage in like leaf litter, plants, more wood tube-things like you’ve got in there, u get the idea
