It's baaaack.

Long after last summer's "Montauk Monster" rotted away, another mysterious animal carcass has washed up on a Long Island, N.Y., beach.

Montauk-Monster.com, which bills itself as "The Official Montauk Monster Web Site," announced over the weekend that a hairless, bloated body was found by a local couple in Southold, on the island's North Fork.

"The beast smelled like a mix of low-tide and rotten garbage. It really smelled horrific," wrote Montauk-Monster.com blogger Nicky Papers. "I couldn't help but take numerous pictures of it and video clips."

Papers then goes on to speculate that the dead animal may be a result of biological warfare, and carrying the H1N1 swine-flu virus.

Last year's Montauk Monster looked to be a drowned raccoon; from the photo, FoxNews.com thinks this one may be some kind of rodent.
