How do you do a "stylish" move in battle?

You can only get a 'stylish' move when you have perfect timing with the action command.

E.g: If Mario uses jump, there would be a button on the left side of the screen which says 'A'.

Press it at the exact same time as it goes down.

When you use Goombella's Tattle attack and align the cursers exactly, you will sometimes do a stylish move.

I think you have to go somewhere and pay this guy and you can do stylish.

All bogus, you press it right before or right after you make contact with the enemy for Goombella, as soon as you aling the cursur, then press A again quickly.

In Rogueport's central area, there is a merchant who will sell you various things. One of them is a badge called Timing Tutor.

When you equip it, a ! will show up in battle whenever you can do a stylish move. To do it, press A. Some have more than 1. Piercing Blow and a few other badge moves have 4!!

If you press A when you land on an enemy after Mario jumps after the 1st stylish move, you will see a 2nd hidden !.

This is also true for spring jump. When you successfully perform a stylish command, you will get more star power.

Uh, I can't tell you the exact timing, but if you equip the Timing Tutor Badge, an ! will appear over your head when it is the time. If you hit A then, you'll pull it off.
