The Bloop was a sound that was heard by the scientists in NOAA (Well, a few heard it), which was pointed out to be either the sound of Cthulhu's wailing, or a freaking mermaid. And that's very creepy. These mermaids seem to be creepy. Very. OK, off-topic. If you want to know more, go to Wikipedia.
Crap, "the bloop" was scary as hell!

Did that mermaid make "the bloop" again?
