Unu (or ウーオ, (Ūo) in Japanese) is a common enemy found in every game of The Legendary Starfy series except Densetsu no Starfy 4. It is a red-finned black fish with a white stripe. The Unu is worth one point in Mini G's mini-game Fishing Derby. If they see Starfy, they will get angry and swim towards him then move back. It is a very simple enemy, so they take one hit to kill.
