The Star Spin is Starfy and Starly's main attack. It is known in Japan as Spin Attack. Starfy/Starly spins around to attack enemies or break barriers. If they spin too much, though, they'll get dizzy. and they can't move for a few seconds. If the player moves the control pad around, their dizziness time will shorten. Starfy's Star Spin can be upgraded to Mighty Star Spin then Ultra Star Spin later in the games.
Normal Star SpinEdit
The starting Star Spin. This Star Spin can break blocks without being bumped, but Starfy/Starly move slower while using it. It is used on land even after Starfy upgrades to Mighty Star Spin and Ultra Star Spin. Starfy can also still use it in water if he spins without moving.
Mighty Star SpinEdit
Known as Spin Attack level 2 in Japan. In the Game Boy Advance games, Chuta always taught it to Starfy. It can get through fast currents and Starfy moves faster while using it, but breaking blocks also bumps Starfy so it takes longer to break a row of blocks than it does for even the normal Star Spin. Starly never gets to use the Mighty Star Spin.
Ultra Star SpinEdit
Known as Spin Attack level 3 in Japan. Starfy moves fast and doesn't get bumped by breaking blocks while using it. It is taught to him by Gekojii in Densetsu no Starfy and Densetsu no Starfy 3, Gekyojii in Densetsu no Starfy 2, Jojiro in Densetsu no Starfy 4 and Herman in The Legendary Starfy.
