Create a fun and whimsical clipart of an iridescent kelpie submerged in water, surrounded by bubbles or seaweed. The kelpie should be the center of attention, with a cartoonish style featuring bold lines and bright colors. The contrasting background should be plain, allowing the kelpie to stand out. Think of the kelpie as a friendly creature, eager to make new underwater friends and explore the depths of the sea.
