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.

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

Rabbits with black, hornlike spikes growing on their heads and other odd or unslightly protuberances are not dangerous and won't infect humans or other species, Colorado Parks and Wildlife said Wednesday, following days of social media posts about sightings of "Frankenstein bunnies," "demon rabbits" and "zombie rabbits" in and around Fort Collins.
