Rabbits spotted with "tentacles" or horns growing out of their heads. But it's really happened in Colorado. "There are really rabbits with what look like tentacles growing out of them," USA Today reported.

Rumors spread online that rabbits infected with a virus that creates a tentacle-like growth on their faces were "invading" the U.S.

The cottontail rabbit papillomavirus, which alarmed some Colorado residents, cannot spread to other species and often goes away on its own, according to experts.
