Geoff was dressing up in his bathroom. He sprayed himself with white fur dye, and darkened the fur around his eyes for a sunken look. He slipped on tattered white shirt and jeans. He battered his fur around trying to give it a messy look, then grabbed the greenish-grey fake blood he mixed up. The fur on his right forearm was trimmed to expose the large scar, and he slathered the fake blood over it, allowing it to flow and dry into the white-dyed fur.
The costume wasn't very accurate of a ghost, to him, but it was the closest he could make it to where the others would get the idea. He then staggered out of his apartment.
