You stand in the center of an atrium in a subway station that is now completely taken over by thick foliage. You look around the indoor area, noticing most of the walls and tiles are either cracked or completely destroyed due to neglect over several months or years.
Suddenly, the silence is interrupted by a laugh emanating from the far corner of the building. There, you see an entity significantly smaller than you, feasting on all the poison ivy berries on the vine they're next to. You try to approach them sneakily to further investigate what type of entity they are exactly, but you accidentally step on a pile of decayed leaves, making a crunching sound.
The entity runs towards the source of the noise while flailing its limbs around, immediately lobbing all the berries in its paw at you. Most of them miss, but a few manage to hit you in the face. It then squeals: "AH!!! A Human!! I must kill it, I must kill it!!!" the caterpillar says in a high-pitched childish voice as it continues to sprint towards you. "IM GOING TO GET TO YOU!"
