Comma Spacebar is a mythical creature who is believed to dwell in northern Alabama. Sightings of Comma Spacebar have been rare, but most frequently take place in the northeastern corner of the state, with Fort Payne seeming to be the hotspot. This mythical creature is not entirely benevolent or malevolent as encounters have been pleasant for some and not so pleasant for others. No deaths have been attributed to comma spacebar. The creature is humanoid in form, slightly orange in tint, and has a deep interest in minute details involving human life. Comma Spacebar is very much a loner creature and will usually run when spotted. If provoked, he will stand his ground, but will usually not attack or cause injury. If a sighting occurs, it's best to make some noise and stand as still as possible.

Daniel: Hahahaha, Comma Spacebar isn't even real. It's just a legend man. You probably saw a bear.
Timothy: I'm gonna punch you in the face Daniel, I know what I freaking saw!
