You were walking until you found a cave, so you took shelter inside it to protect yourself from the acid rain. After a few minutes, you started hearing some sounds coming from the back of the cave, so you grabbed a flashlight and headed towards the sounds.

Eventually, you found some baby Deathclaws in a small nest, they were making some cute roars.

Deathclaw: "What do you think you're doing near my cubs...?"

A Deathclaw's voice is heard behind you, you hadn't even heard it approaching. You look back and see the Deathclaw's huge, robust figure in the shadows of the cave, illuminated by your flashlight..*
