Dash: push joystick twice quickly then the A or B button
Move in on your opponent and press A+B buttons: POWER ATTACK
Move joystick left/right and press A repeatedly: MALEVOLENT MOVE.
C+A or C+B button: JUMP
Press B or C when your opponent hits the canvas: PIN
When the Power Gauge appears on the screen, push A continually to raise Power. When the attack signal is displayed, drop your opponent. Use the combinations to drop your opponent
Lots of special items can be found by throwing enemies into the background and breaking things.
Massive throw damage: When you grab an enemy, pressing Up on the joystick followed by the Attack button will make you throw the enemy onto the background, dealing quite a bigger amount of damage than the regular side throw; and in some cases (like in levels 2 and 3), it'll allow you to kill an enemy with a single move.
It's actually any 2 directions + A, and the directions pressed will affect the arc of the ball. And yes, you can make the ball big enough to cover the entire screen; do it fast enough, and it will prevent you from picking up any teapots, which gives you a special bonus (multiple tech sphere bonuses will appear). On later levels, those spheres are worth more points.
(tap same direction twice) + A - make a ball that you can grab and throw, you can make the ball bigger by hitting it with another ball.
back, forward + A - rapidfire
forward, back + A - triple shot
f, fd, d + A - arcing rapidfire downwards, from front to back
b, bd, d + A - arcing rapidfire downwards, from back to front (Cotton Boomerang only)
f, fu, u + A - arcing rapidfire upwards, from front to back
b, bu, u + A - arcing rapidfire upwards, from back to front (Cotton Boomerang only)
b, f, A, b, A, f, fd, d, A - rapidfire, triple shot, TWO arcing rapidfires (both upwards and downwards at the same time). f, fu, u, A in the end also works. (Cotton 2 only)
b, f, A, b, A, b, A, f, A - rapidfire, triple shot, TWO arcing rapidfires, then summon a dragon (Cotton Boomerang only). I just spam back + A then forward + A once the combo starts.
All the above combos will seal an enemy automatically, if they do the kill hit.
f, fd, d, db, b + B - grab AND seal the enemy (this is your default grab in Cotton Boomerang)
f, f, b - make Silk or Needle (the fairy and the living hat) take off or settle down on you. They automatically take off when you are hurt a lot. Cotton 2 only.
b, f, b, f + C - remove one of your magic slots, without producing a special attack. Cotton 2 only.
up, uf, f, fd, d, db, b, bu, u, down + A + B + C - suicide
Hold A - move faster
Hold A, double tap direction - dash in a direction (Cotton 2 only)
Hold A, release - summon a dragon (Cotton Boomerang only). This one has a long cooldown, but you can spam the combo that ends with a dragon, then do this hold move, and you can spam dragons nonstop. It's important because the dragon cancels incoming fire.
