I'd thumped and nobody had thumped back. That meant there couldn’t be any rabbits inside. No bunny can ignore the challenge of a thump. But, there could be other animals hiding within the cave. Bad animals. Animals who could hurt a bunny, even if the bunny was the Queen of the Other World.
I'd stretched as far as I could go to try to see into and around the cave, but nothing showed itself. I took a deep sniff of the air surrounding the cave. It had a weird odor -- like no other dirt I had ever smelled. The combination of human and something else caught my senses. Should I take a chance and enter the cave? My heart bumped against my chest as I made my decision.
