First of all: Hello! I am new here. Nice forum.

Its a really old movie that I saw when I was a kid and it scared me really badly. A family living in a house discovers that there are creatures living under the house. These creatures are like evil gnomes that are midget sized. The faces closely resemble the Sleestaks from the old TV show "Land of the Lost", even the heads are pointy. Probably only about a couple feet tall.

There were some scenes where the creatures were watching the inhabitants from behind these floor-level heating grates. The people would look into the grates thinking that they see something move. It didn't help that we had these kind of grates in the house where I grew up. Many times I swear I saw these things in our grates!

Unfortunately, the only scene I remember is at the end when the last surviving member of the household was dragged into the heating grate by these evil creatures.

Sorry, I know that isn't much info but thats all I have. So.....name that movie!!!

Thanks in advance!
