Anyone see 'Cloverfield?'   It wasn't in the movie, but in the internet back-story theres some substance they find at the bottom of the ocean!  The japanese discovered it, and put it in a drink called Slusho....

Supposedly, this is what was in the exploding tanker in the harbor at the beginning of the movie.  And it may have led the giant monster to Manhattan.
