This is the Snilby, a character I created a few years ago for an animated series pitch called "Quiet, Please." The story takes place in a library in Hell, and the Snilby leads a grim life toiling for the shelving demons.
This is a new drawing, because I figured out some upgrades for the Snilby, such as the tape-dispenser butt, glue horn, and staple bite. I think he's even more efficient now, and every library should have one.
