The Gunk Monster is hard to miss. It’s a beast that is extremely agile and fast. Many people report being unaware of its presence until it was too late.
It is a shape shifter, meaning it can transform its appearance at will. Most commonly it will appear as a black, greasy mass.
The Gunk Monster has also been seen with another creature that looks like a shambolic collection of rusted metal parts and debris. This corrosion creature is more elusive but can be equally as damaging to engines.
