The “Muriwai Monster,” a twitching black mass that washed up on Muriwai Beach, 25 miles northwest of Auckland, New Zealand, has taken the world by storm since its discovery about a week ago. Melissa Doubleday, who stumbled upon it while driving by, initially suspected it to be a whale carcass. However, when she shared images of the mysterious “creature,” which was covered in seaweed and wiggling black tendrils with white shells, on social media people around the world began speculating it was a sea monster, a “beach Christmas tree,” or even an alien time travel capsule.
