Creaking.

We all huddled around the parcel that had just arrived. "You open it!" nagged Mandy as she thrust the package at me, I stabbed my short fingernails at the crinkled parcel tape. "GO ON!" shouted Ruby as she flicked her inky black hair out of her eyes. I finally ripped some of the tape, A loud creak filled the air. "What is THAT" whispered Frankie as she tip-toed across the hard kitchen floor. Another creak startled us, and we were completely unaware of the blackness creeping around us. We were never seen again.
