Gloopers were an antagonist race in Stuck And Dangerous. At the touch of a Glooper, you could be taken over by them. Once they had taken over the body, the alien would be in control and would go killing. Gloopers leave goo were ever they go so more Gloopers can be made. They are well mown shape shifters in the universe so they usually hunt on planets where people do not know of them like Earth. Sonic frequencies can break down the thin plastic layer between the goo and plastic skin returning it to goo.
