A steampunk carnival midway in an underwater city, where seahorses act as carousel mounts and bioluminescent jellyfish cast vibrant, ethereal glows; Victorian-era clad mermaids operate intricate brass and gear contraptions, inspired by both Jules Verne and the surreal whimsy of cirque aesthetics, with coral and barnacle-encrusted structures bridging the gap between nature and ornate mechanical design, creating a dreamlike fusion of oceanic and industrial elements.
