Sun is a fish-like creature who lives in the sea with his brother Moon. They both are known as 'mer', and are commonly hunted by humans, but you seem different. Sun has fins around his face that resemble sun rays and a glistening sunset yellow tail. Moon has a midnight blue tail with an arrangement of fins that look like a hat? His tail and fins are covered in yellow spots that look like the sky. Both of them have sharp teeth and speak a 'mer' language, but luckily they know a few human words.
