This is a strange and hostile alien species. It isn't known where they came from or why they invaded Earth. Their invasion started with Tokyo all the way to New York.
The Slime Creatures flew around in flying saucers that could withstand atomic bombs. It was revealed that they could shoot death rays out of their eyes and blow people up with them. It was also revealed that they would mate in the sewers. Their skin looks like a lizards' and also is covered in slime. Their hands have been described as "all covered in fungus" and they were also noted as "really [needing] some manicure". The eyes resembled a bug's eyes. They could also suck out human brains through a straw.
