When I was younger I wanted to rent out a cartoon but the video store lady put the wrong one in the vhs case so I put it on and it was a horror movie about a family that is attacked by monster(s) that melt into transparent jelly liquid. I don't remember anything except a scene where the monster melts onto floor into liquid in the family's house. I just know it gave me a lot of nightmares but I was only 5 or 6 years old so maybe it wasn't a horror movie. Maybe it was just scary for me. I don't know...
Does anybody know what movie is this?
