Wall Jump is an ability only Starly can use. To use it press the B button near a wall. Press the A button for the Game Boy Advance game. It is taught to her by Kittana in Densetsu no Stafy 3. Then by Shurikit in Densetsu no Stafy 4. Starly does not forget how to use it in The Legendary Starfy. For some odd reason, Starfy can't use it. This move is also in Mario, Metroid, Sonic, and Super Meat Boy.
