Small Snake
Oh god, what is this?! ….
I see them all raise their arms up before the entire lake itself starts glowing with a deep blue light. It seems to be pulsating akin to the heartbeat of a titan. In there I can see the remaining goldfishes flash brightly before starting to vanish.
What is happening?! With every fish disappearing the very water below me shakes, all a precursor to what is to come. The calm lake is no more. That is when it all raises in the air before forming a giant shape in the air.
There is a serpentine-looking humongous body, a gaping maw that can clearly devour me whole, shiny stars in place of eyes, and it is roaring like a waterfall. It's a goddamn dragon! One entirely made of water that looks deadly enough to kill anything in existence.
