How do you defeat Captain Whiskers On Sonic Rush adventure

Captain Whisker and Jhonny are together as the boss of Pirate Island. Beat Pirate Island Act 2 to get to the boss battle. once there, it's always easier to take out Jhonny first, then the Whisker. Be careful that there is a saw that comes down the 4 floors of the field. First it will start on the highest level and work its way down. It's always easier to fight on the 1st floor, but if you run low on rings wait 'till saw comes down to the floor that you wont go on and go on the floor that doesnt have the saw on it but has the rings on it. Good 'nuff? Good luck.
