Lol Giant Rat That Terrorized Family Killed At Last (WARNING: Graphic Image)

A Swedish family's three-week nightmare is over: Ratzilla has been killed.

The gigantic rat that invaded the home of Erik Korsas and Signe Bengtsoon and set up shop under their kitchen sink was dubbed Ratzilla by the news media.

The couple suspected there was some kind of animal invader, but they didn't imagine an oversized rodent was in their midst.

"We thought it could be a little mouse, but after a while we figured it couldn't be because it was making too much noise," Bengtsson told The Local.

She got the shock of her life a few days later when she discovered the mutant gulping down leftovers under the sink.

"It was right there in our rubbish bin, a mighty monster. I was petrified. I couldn't believe such a big rat could exist," she told the website. "I couldn't help but do the old classic and jump on the kitchen table and scream."

The pest apparently got into the kitchen through a ventilation pipe, after gnawing through cement and wood.

Ratzilla was so horrifying that the family cat refused to enter the kitchen, the BBC reports.

Eventually, the rat was trapped by its neck, but took its sweet time dying, preferring to crawl behind the dishwasher for its final moments on Earth.

The carcass measured about 16 inches in length, not counting the tail, and weighed around 2.2 pounds.

"The kids were afraid it would come back to life as some sort of zombie rat. They didn't want to touch it," Korsas told The Local.
