Rock Chuchu

, also known as Rock ChuChus, are recurring NaN Enemies in.

NaN Rock Chuchus in appear on TMC: and TMC:. They are NaN Red Chuchus that wear rocky helmets over their faces, protecting them from most of TMC:'s attacks. They do not jump, and their helmets can be destroyed by various attacks, including the TMC: technique, turning them into regular NaN Red Chuchus. A TMC: can also be used to defeat them instantly.

NaN Rock Chuchus reappear in, though their rock helmets are now designed to look like regular rocks. They act the same as in and are defeated by the same methods. The PH: and PH: items are able to defeat NaN Rock Chuchus as well.
