Explorers on a tiny raft drift across an underground ocean beneath stormy clouds past giant mushrooms and prehistoric reptiles

Prompt

Journey to the Center of the Earth — The Underground Ocean

After descending through volcanic tunnels, the explorers emerge onto the shores of an immense underground sea stretching beyond the horizon beneath a cavernous ceiling filled with glowing clouds and crackling lightning. Towering mushrooms rise like forests, colossal prehistoric reptiles battle in distant waters, and strange mineral formations shimmer with ghostly light. Their tiny raft drifts across this impossible world, where every direction reveals wonders untouched since Earth’s earliest ages.
