90s movie- family goes to western town and people have green goo in them
There is a family with parents and a daughter and son. There are clones or something of everyone also (but they are made of green goo). I think they have to sign into this guestbook in the hotel they stay in as well, and if they don't they get in trouble haha. Um one scene the daughter has to roll up the window in the car to prevent her "mom" from getting in and her arm ended up getting cut off and the green stuff got everywhere. THIS IS KILLING ME that I can't figure this out.
