The unusual appearance of the rabbits has drawn significant concern among locals and even social media users online.

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.

Northern Colorado—specifically a town called Fort Collins—has recently made headlines for its rabbit population after it was revealed that several of them had long black tentacles growing all over their bodies.
