Shade yipped with excitement at the sight of a tunnel. It loved the underground and was eager to get in. Scarcely pausing to wait for it's friends it turned into a bat and took off down the tunnel, stopping halfway in to call back to the others;
"Come on! What are you waiting for?"
Shadow soon zoomed in after it and together they whizzed onwards, dodging any obstacles that got in the way with incredible agility.
Wonder if the humans need a torch, thought Shade absentmindedly, can they see in this?
Ah well, I'll think about that when I start hearing the "oofs".
