Each character has an unique special skill that can be used for an advantage throughout the match. The special skill is different for each character and it slowly charges up over time. When it is available, the picture of your character will be blinking red. Hit the blinking button to activate the skill. Sometimes the skill is only available at a certain time (i.e. during putting or when the ball is in flight) and thus can only be activated at certain times. From the character select screen, you can click on the special skill to find out more information about it (the button under your character's skills).
