The Sears/Kmart exclusive ringtone, titled "What Was That", is a mix of Marlena and monster roars. You can download an MP3 of the ringtone here.
The WhenCloverfieldHit.com site also had some great Cloverfield sounds, but I didn't realize the links were taken down when the contest ended. Fortunately, you can still downloaded them all directly:
