Ariel is having a peaceful slumber on a bed of seaweed surrounded by the tranquil ocean. In her dreams, she is gracefully swimming and playing with her friends Flounder and Sebastian among a magnificent, colorful coral reef. She looks beautiful with her long, flowing red hair billowing out into the water and her distinct pink seashell bra and green fishtail glimmering in the sunlight. To complete this dreamy scene, one could give Ariel's tail and seashell a bright teal hue, her hair a mix of fiery reds, oranges, and yellows, Flounder a brilliant yellow, and the coral a lively array of pinks, purples, oranges, and blues. It's sure to make an incredibly vibrant, delightful image!
