I looked down and there they were we were watching them, coming up the ravine and using their own bodies too balance themselves they were able to cross the river , incredible . Due to an overuse of chemicles and dumping the empty cans where we pleased these things grew in size ,it seemed all the major cities were in fact hit first with this .

First New York, Chicago, then Dallas  ,they had continued to spread out,  their normal size would be no bigger then a thumbnail or slightly then a finger .They were actually called slugs.

Now they were the size of a small child .

And they continued to spread .

end,one shot story .
