Kurikuri is the original Japanese name for the character often called Clicli in the English version of Marine Boy. He is a boy who hails from an ancient underwater kingdom and appears as a recurring ally across several episodes. By nature he is cheerful and deeply inquisitive, always curious about the world around him and eager to learn new things. His motivations are rooted in a genuine desire to help Marine Boy and the Ocean Patrol whenever dangers arise, and he willingly inserts himself into situations where his knowledge or companionship can make a difference. Although he is not a main member of the crew, Kurikuri plays a reliable supporting role, frequently stepping in to assist Marine Boy in getting out of trouble or providing timely help during missions. His primary relationship is with Marine Boy, with whom he shares a friendly and cooperative bond, and he functions as an occasional companion rather than a fixed partner. Over the course of his appearances Kurikuri does not undergo significant personal change, instead serving as a steady, good-natured presence whose helpfulness and upbeat temperament reinforce the show's overall sense of camaraderie. He possesses no extraordinary powers or special equipment, but his background from an ancient undersea civilization gives him a unique perspective and makes him a useful friend when the story ventures into hidden or forgotten parts of the ocean.
