This is horrible!
This footage has come out of Taiwan, filmed by Wei Cheng Jian, and it is terrifying!
The horrible bright green blob is an unknown worm thing. About a metre long, it wriggles around on the floor, and seems to excrete some weir slime stuff, as well as another little pink worm coming out of the front.
People of the fishing port Penghu have been scared since the thing was found.
If you somehow have any idea what it is, feel free to let us know in the comments!
