I know Slimer was bigger in GBII, and for the most part was just a model or a maquette in gb1, but fictionally about how big was he suppose to be?
Slimer’s size in Ghostbusters II matches up more or less with the size of Slimer in Ghostbusters when Mark Wilson wore the suit during effects photography. It was from head to stomach. But they used oversized props so when composited with live action, Slimer was made to appear smaller than human-size like the large clay figures made by Steve Johnson. So fictionally, he was actually more the size of a dog like an English Bulldog.
Nevermind.
I grappled with this while planning my Slimer sculpt that I’m making. I went with a GB1 estimate. By my guestimates, I think he is about 30-32 inches tall from top of head to bottom of belly.
Ive always thought of him being the size of a small child. You can still hug/hold him but hes not tiny.
I just figured his size based off the food stuffed in his mouth
