Low Spin
From Starfy Wiki
Low Spin is an ability only Starly can use. It is translated in Super Smash Bros. Brawl as High Hat Spin Jump. To use it press the Y button while crawling. It is introduced in Densetsu no Stafy 4. When using it, Starly lifts her arms and spins super quickly on her stomach. It's a great way to dodge high attacks or go under flying enemies. Another technique is to find a crumbly wall and low spin through it. This will prevent enemies from following you and attacking. Yet another technique is to low spin to evade a fast enemy with low spin's extreme speed.
