The Power Bowl Ghost was an entity that terrorized patrons at a bowling alley.
Based on appearance, the entity is the spirit an unidentified person who used to bowl at the Power Bowl bowling alley. As a ghost, it did the opposite and attacked fellow bowlers often with familiar implements such as bowling pins. The week before Thanksgiving 1997, the Ghostbusters were called in to capture it. Peter convinced the original team to handle the bust for old time's sake. After getting used to the modified Proton Packs, the team easily trapped the Class 3.
While the original Ghostbusters head to the basement to deposit the ghost into the Containment Unit, it is stated the ghost was a Class 3 Semi-Corporeal.  It is also a Full Torso with a Vaporous bottom half.
His grotesque spirit form suggests that he was probably not a nice guy when he was alive.
