My World Of Hopes, Dreams, Fantasies

Pond, Dark Opaque Surface

Prompt: Imagine a pond with a dark, opaque surface in your backyard or in your neighborhood. Can you imagine what is underneath that surface?

I hope something friendly like a manatee, beautiful fish, dolphin or a magical key to unlock the problems of the world or make a better place. I like stories of sea monsters but I don't want to encounter one unless it is friendly. Anything beautiful or good to help mankind would be beautiful to find underneath the pond. Maybe a mermaid who can grant me 3 wishes. I would love it. Maybe a pirate treasure chest full of nice things. If it is something evil, it can just stay!
