Slimer is a translucent green mass of a ghost, with two skinny arms, no feet, several chins, and a massive butt. Slimer’s personality is one of tremendous gluttony, being referred to as a “disgusting blob”, and exists only to eat food [or to create mischief]. The only downside to this is that the food passes right through him, which is most likely why he's perpetually stuffing himself.

"Ghost Class" wise he is referred to as a "focused, non-terminal repeating phantasm, or a Class Five full roaming vapor".

He is first seen haunting a room service cart on the 12th floor of the Sedgewick Hotel, and according the manager, had been there for years.
