This bright green, slimy sea creature is giving the internet nightmares

What… is it?

Here's something new to haunt your dreams…

A video of a mysterious long green sea creature has been doing the rounds online as people recoil and collectivively ask 'what the hell is that?'.

The footage was shot in Taiwan by Wei Cheng Jian who was fishing in the port of Penghu when he spotted the alien-looking creature.
