While possessing Louis's body, Vinz was able to speak, but not coherently and was in a disoriented state. Vinz possessed Louis while the people inside Tavern on the Green resumed their discussions. Louis screamed in terror then slid down to the ground and fainted. Louis tried to talk to him like a person to a regular dog and frantically checked his pocket for a Milk-Bone. Vinz Clortho caught up to him and cornered him at the Tavern on the Green. Vinz hopped over the wall into Central Park.

He knocked the Doorman over but avoided contact with a nearby couple narrowly. Upon spotting the hellhound crouched outside, the old dear exclaimed in shock and wisely hotfooted it back inside to call the police. The elevator arrived and Louis got in and pressed the button for the ground floor just as a door down the hall opened and an elderly woman came out to investigate the commotion. Outside, Louis ran to the elevator as Vinz came barrelling through his apartment door as well with a loud crash, also managing to damage the door directly opposite. Louis also screamed then fled out into the hall. The guests screamed, scattered, and cowered as Vinz focused its attention on Louis. He landed right on the refreshment table, demolishing it completely. Vinz burst out from Louis Tully's bedroom during the party he was holding for his clients. Confused as well, Louis turned and said, "Okay, who brought the dog?", apparently under the impression that one of his guests had somehow managed to smuggle their pet into the party.

After Louis asked if anyone want to play Parcheesi, everyone heard a growl.

He threw Ted and Annette Fleming's coats toward his bed and it happened to land on Vinz's head.

It growled softly as he finally opened the door, but he didn't notice it. It ended on up on Louis's bed and waited for him. Vinz Clortho manifested on Earth in a couple weeks later, on a Thursday night, after Zuul, on the roof of 550 Central Park West as a large horned beast with vicious red eyes known as a Terror Dog. When Dana noticed it, causing her to scream in horror, slam the fridge door shut and seek the Ghostbusters for help days later. Vinz Clortho appeared inside her refrigerator, the contents of which were replaced by another dimension also inhabited by the Temple of Gozer and Zuul. In 1984, Vinz Clortho first appeared at Dana Barrett's apartment as she returned home with groceries.
