These are a couple of the mysterious creatures found in the red pool in the endless basement.
The endless basement runs underneath our world with access points in many locations around the globe.
I stumbled into the endless basement through a dream and have explored many of its rooms and corridors.
In one corridor, 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 don't know how far the pool extends, however I did notice that the faint glow was coming from deep down.
One day I shall return to the pool and investigate more.
