The underwater cave is dark and rocky. Inside the cave fish and tadpoles have taken over. The water is cold, no light gets in. Once inside, a rocky outcrop allows swimmers to come up for air.
Underwater Cave, Cave

I love swimming in the river with the other fish. Mostly I spend my days looking for smaller fish to eat. When people cast lines into the river, we all swim away from them and hide. Sometimes one of the other fish gets confused and bites down on the lures.
Wait...don't bats like caves... But this cave is underwater. I can't fly out to hunt! Well I got here by swimming, but how did you get here? I honestly have no idea. It almost seems I was plopped here by a supernatural force.  How strange, whoever would do such a thing. Maybe I crossed a witch or warlock in my travels.  Well certainly there should be something for you to eat here? I eat smaller fish myself. Alas, I cannot swim! I don't suppose there are any bugs in the water? There might be some floating around I have never paid much attention to smaller things. I don't suppose you can help push some in my direction? I am trapped on this rocky outcrop.  Apologies that I cannot be of more help as I am restricted to the water. Anything you can find would be extremely helpful! If you were not here, I would quickly perish from starvation!
