A slug

As the asteroid came crashing down to earth and collided with the forest, a strange creature emerged from within. It was an alien slug, unlike anything ever seen before by mankind. Its slimy body shimmered in the light, and its two eyes swiveled around, taking in its surroundings. The creature seemed harmless enough, but its arrival on earth spoke of something else.

The slimy, green alien slug wriggled on the forest floor, its bulbous eyes scanning the area for any signs of danger. Suddenly, it sensed movement and tensed up, ready to defend itself from potential threats. As the footsteps drew closer, the slug braced itself for a fight or flight response, but to its surprise, a human figure emerges.
