This odd ooze has arisen, bubbling up and congealing. It consumes and sticks to everything it touches, like a tarry gunge that spreads. Everything in its path has been consumed and covered by the slime, but nobody knows where it came from or what it wants, just that it keeps eating and eating, growing ever bigger as it eats and eats.
You thought you could escape in the forest, surely there would be enough out there that you could hide, or run as it ate everything else behind you. Just when you thought it was safe, you turned around and saw the puddle forming. It bubbled up, small at first, then gurgling and splattering as it grew. There was no time to run, as you stood there watching in silent awe.
Just as you thought you might drop from the fright, the ooze took form. The shape of a monster girl dripped through the icky muck, calling you in. You thought she needed to be saved, as she reached out, beckoning to you to grab her hand to pull her free. She consumes all.
