Yes, Head Toward A Swamp

"I think there's a road up ahead. Maybe if we can get there, we can... ew!"

Your leader stops in her tracks, a loud shlooping noise echoing through the trees as she lifts her foot from a barely visible puddle of mud with a look of disgust on her face. Your eyes scan along the ground and you see more puddles and moist terrain all around you. Somehow, you've managed to stumble into a swamp. Your female companion stops for a second and reaches for her filthy shoe.

"Ugh, it's all covered in mud and... is that a slug? Augh!"

She chucks the shoe to the ground, clearly nauseated by the thick black slug crawling across its side, and stands there on one foot looking at you like she expects you to know what you're supposed to do now. You try to innocently turn your eyes away from her and they land on her shoe. However, the slug on it isn't just crawling anymore. It looks more like it's... flattening, spreading across the surface of the shoe. Fascinated, you can't pry your gaze away from it as the slug spreads further and further, its slick black surface perfectly matching the shoe's contours and sliding inside of it. Once the shoe's been covered, its shape starts to wobble, shivering and shaking just as it sinks into the mud and out of view, leaving its fate a mystery.

"Er, are you okay?" Her question pulls you out of your trance. "Hey, what happened to my shoe?" Ignoring her question, you look at the ground around you, and suddenly you realize that the slug that had covered her shoe wasn't the only one here. Behind you, along the forest floor, up and down the trees, slugs dot your surroundings. The girl goes silent, and you know that she's seen them too. The slugs start approaching you, slowly making their way closer until the closest ones are only a few yards from you before you finally turn to your travel mate and lay it down.

"We need to run."

"But I only have one shoe, and the-"

"Now!"
