A vibrant and whimsical underwater scene depicting a school under the sea, with a sprawling coral reef serving as the backdrop, featuring a sprawling, winding staircase leading up to a majestic, ancient-growth kelp-encrusted entrance, adorned with glowing jellyfish lanterns and schools of iridescent fish darting about, while a diverse group of mermaid and merman students, each with unique skin tones and tail colors, ranging from shimmering turquoise to radiant orange, sit at intricately carved wooden desks, surrounded by floating seaweed-covered textbooks and curious sea creatures, including a wise-looking octopus teacher with spectacles perched on the nose, amidst a kaleidoscope of colors, with shades of blues and greens dominating the palette.
