Oh man, I am so curious right now I could walk all the way from here to your place!
You got me hooked to this topic!
I would definatly try to make pictures or film it!
Try a stealthy setup of camera's (and maybe together with motiondetectors)
If you know where it walked before try to lure it to walk there again, but then into the eye of a camera.
My best regards, Kodiak.

If you really must know who that is, I'll give you a hint:

Old Tom Bombadil is a merry fellow
Bright blue his jacket is, and his boots are yellow.

I say put out more wood for him to split if he's willing to do it.
Don't look a gift horse in the mouth.
