The crab dived into the hole like it had done it a thousand times before, smooth and effortless.
I narrowed my eyes and my expression grew serious. "Let's go," I said to Steve without looking back.
Without waiting, I followed the crab down into the dark tunnel. Steve swam right behind me.
Before entering fully, I released my hold on the water bubble that had let us talk. The water rushed in with a loud splash, crashing through the hole and flooding it completely. Now, we were fully submerged again.
The crab didn't swim too far. After about ten meters, it came to a stop and just floated there, blocking the tunnel like a bouncer at a secret club.
Steve and I came to a halt right in front of it. I tilted my head, waiting to see what it would do next.
The crab slowly raised one claw, then the other, and waved them around with exaggerated slowness—like it was trying to give us directions. One claw pointed further down the tunnel.
Steve elbowed me in the side and gave me a look.
