I decided to create a story of sitting by a crackling fire. At the beginning you hear footsteps walking away from the fire. I recreated the popping noise from the fire by tapping/scratching my nails against a small pumpkin I have in my room. I did that a few times and overlapped the audios, some sound louder than others. You can also hear beeping in the background, which was unintentional, there was a fire alarm going off somewhere close by.
