what was different in the theatrical version of GB2?

At the end of the version shown in theatres, Slimer comes out from behind the Statue of Liberty and goes right into the camera (as he did at the end of the first film). The video version just ends with a pan up to the statue's head, then, a fade to black.

Two attempts by Louis to capture Slimer. The first involved several Kentucky Fried Chicken legs strung up to the firehouse ceiling. Slimer comes out and grabs a leg, and Louis pushes the button for the trap. The light comes out, but Slimer floats out of the way and the ceiling collapses, falling on Louis' desk. The second attempt involves Louis carrying a proton pack and faking a pizza delivery (“Oh, hello, Pizza Man! Oh, two larges! I only ordered one. Oh, pepperoni and pineapple. I guess I'll have to eat these both by myself”.) Slimer floats down from the ceiling, and Louis tries to shoot him with the proton pack. Slimer flies away, and the beam flies towards Janine carrying a stack of files, who casually steps aside of the beam.

Many scenes that were shown in theatres back in 1989 were cut when it was released on home video.
