Walkthrough

This time the battle will be harder than Morello, but still nothing that keeps you for hours trying again and again. The easiest way to beat him is by keeping all the power-ups until you have three. Then throw the first one, wait until its damage is totally done and proceed with the other two. Throw them when he is doing a big solo, and you'll beat him. A good time to use any power-up is when he has a long string of rapidly repeating red,yellow, and blue notes. A whammy bar power-up or even better a double note power-up there will probably finish him off. A good and fast way to beat him is getting the first powerup in the battle.
