Go to Edit Skills from the Main Menu. Go to Edit Capsules and choose the skill SENZU BEAN in the custom tray of any charachter. There are total 7 spots in the custom tray and this skill takes up 3 spots so choose your other 4 skills wisely. Now fight in any mode (duel, world tournament, dragon world). When you are fighting some tough charachters you might die. But you as soon as your life ends you will get back up and have 3 more bars of life. That makes 6 bars for you. This is extremely useful in Dragon World when you are fighting Super Buu (Gohan absorbed) with Hercule to unlock Videl. Note: When you have entered the BREAKTHROUGH skill in the custom tray of your charachter, the SENZU Bean skill won't come into effect. So remember that you can only use it separately.
