Burn
Very helpful, but when used it only goes straight up, and
no other direction.
Stone Works almost the same as the fireball, since it only goes
in one direction, which is down. It can smash through many
types of blocks and it's helpful when fighting a boss.
Needle Needle can break blocks with ease and it helps when you
want to change direction by using it.
Spark When used, the ball will continue as always, but will
spark and knock out blocks and enemies with ease.
