He lit a cigarette. There might be easier ways to handle the den's inhabitants, but he wasn't going anywhere near these little monsters, not while they were alive.
The hissing stopped. He turned. The creature that clutched the crumpled machine let go, and reached for him.
The cigarette fell to the ground. A single chirp came from the den. The creature crooned in answer, reassuring her baby.
Mother was home, and she had food.
