For the Cheshire Ball thingy. Here is the info I provided:

Cheshire's Name: Phosphor
Trick or Treat?: Trick
Anything Else: Phosphor hides in dark places and only comes out at night. He has a halogen lamp on the end of his tail to help him find his way in the dark. This turns on and off at will along with his other glowing parts, a skill which he uses to trick people (especially children) into thinking they see something they don't. He is frequently mistaken for a will-o'-the-wisp.

yep.
