How do you defeat final level in PAC man world 3

To defeat Irwin's Teratron (up-graded Gigatron) you must rev roll on all four of the rev roll plates, Butt bounce on the cages with blinky and ink. then you must hide behind a pillar because the teratron has a super attack that hits everywhere no matter where you are (except behind a pillar). then you must butt bounce on the glass surrounding Irwin on the Teratron. Be careful of the missiles that he shoots at you they explode and will kill you. they are very easy to avoid if you know what you're doing. And that's it. To get to the teratron you follow the pathway. You will come to an elevator that moves down when you kill all the enemies on that floor. Then you will find a room with laser walls. You go straight ahead and blow up the crate. Then you go back through the disabled laser wall and destroy another crate. beware of the ancient defenders (scorpions) and the lazer things.then go to the other side and do the same thing. then go up front go through the door and then the other door. Hope that helps!
