I found the official plot synopsis:
Rob Zombie the master of horror, revisions a classic tale about a Blob from outer space that consumes people. In this re-imagining, set in texas a family of murderous killers awake on halloween day to find a mysterious blob-like alien named Carl who is cannibalistic and has an appetite for murder and mayhem! Set in the outback west in the 1970's, this new tale is jammed pack with explicit gore and the word "fuck" alot, with an ending so shocking, it will spawn several spin-offs and sequels that will be directed and written by Zombie himself after vowing not to do them, but took a long second look at box office records and thought "why the hell not?" Starring Sheri Moon Zombie, Tyler Mane, Sid Haig, Bill Moseley, Scout Taylor Compton, and William Forsythe as Ronnie White (in his younger days before meeting michael meyers mom)
