Mysterious Creatures

In one corridor of the endless basement, I saw what appeared to be a red "puddle" with a faint glow to it.  Upon closer examination, I found it to be a deep pool with red water and green fibrous algae.  

I gazed down into the pool and was amazed to see a large variety of tiny incredible creatures.

These are a couple of the mysterious creatures found in the red pool in the endless basement.

I don't know how far the pool extends, however I did notice that the faint glow was coming from deep down within the pool.

One day I shall return to the red pool and investigate more.
