Poleepkwa Halloween pt2

A part of a series created by and myself. Black Jack experiences a personalized halloween, of sorts. This has nothing to do with District 9.5 and is probably not canon in the slightest, but I gotta admit, I had a lot of fun helping setting this up. I was hoping to be able to put a series of pics together as a comic strip, but my photoshop skills are nonexistent. So multiple deviations it is.

As darkness fell, and the humans went off to their Halloween party (after trying in vain to get Jack to join them, figuring he'd be quite the attention grabber) Black Jack went for a walk through a nearby forest, for the sake of just getting out. However, he appears to have stumbled across something that has him looking more than a bit rattled. What could it be?

EDIT: Ten points to whoever can come up with a really awesome caption!
