CHARACTER: A ghastly, ghoulish dead boy. Roughly aged 12.  A chip off the old blockhead. Pox is the chaotic middle child of Beetlejuice and Lydia. Quick tempered. Fast talking. Hyperactive, Aggressive. Small but fierce. He prides himself on being a menace to Neitherworld society. His magic or "Juice" often malfunctions. A Napoleon complex.

VOICE : Similar inflections/mannerisms to Beetlejuice, but the optimal word here is "pipsqueak". !!!Pox could be voiced by either a male or female!!! He's high energy, mischievous, he possesses a great deal of vocal fry/rasp and (being prepubescent) he has an occasional squeak. It's by no means an attractive voice. A good voice model might be Dana Hill's work as Max Goof from Goof Troop.
