THAT"S IT !!!!! Suzanne, I knew this reminded me of something specific, and it's an episode of The Next Generation.
Since I couldn't remember the specific episode, it took an hour of scouring my favorite trek resources, but I found the entity; a spaceborne being called Nagilum. (It was episode 202 - Where Silence Has Lease for anyone who's interested)
Cute, aint he. Thanks Suzanne, that was driving me nuts.
