Answer:
Once upon a time, i saw a 12x12 box. It was taped shut, else I'd already be napping inside the box. People around me were being boisterous, so I took the effort to unsheathe my claws to rip the tape. As the box opened, I was horrified to see that it wasn't empty. A horrendous blob immediately engulfed me as I exposed it to the outside world. I was stuck. Let my experience be a lesson to you; do not open mysterious boxes.
