How do you beat Doctor Eggman in Ice Paradise in Ultimate Flash Sonic

Sonic, Knuckles, Shadow and Amy: Best to learn the pattern of the bombs and the speed that they are dropped and explode, once you think you have it memorised, try to hit Eggman just as he drops the bomb and before it hits the ground.
Tails and Cream: These two lucky people can just fly ahead of Eggman and hit him there rather than jumping over the bombs.
