"Create a fantastical image of an octopus where each of its eight tentacles ends

"Create a fantastical image of an octopus where each of its eight tentacles ends in a different brain. The brains should have unique textures and patterns, with some appearing smooth and others more intricate, like coral or crystalline structures. The octopus itself should be vibrant, with a shimmering, iridescent body. The scene should have an otherworldly, underwater feel, with glowing, ethereal light illuminating the brains and reflecting off the octopus's skin. The background should be a deep oceanic blue, with hints of mysterious marine life in the distance."
