Battle

Boss guide
When the player arrives in a wide empty area at the end of Secret Plant Zone Act 2, Dr. Eggman will appear in his vehicle from the right until reaching the center of the arena. He'll then deploy its two platforms with spikes underneath them, one on its right and the other on its left, initiating the boss battle. Eggman will then shoot red balls at Sonic's direction by waves of three following shoots until he's defeated.

This boss needs eight hits to be defeated. Since Eggman is out of reach by jumping from the ground, the player must use the spiked platforms on its sides to be able to reach him without getting hit by the spikes underneath them or the red balls Eggman's shooting in the process. However, by being on the platform, Sonic weight will push both platforms to move either in a clockwise or counterclockwise fashion based on the platform Sonic is on (with the one at the right of Eggman going clockwise and the one at his left, counterclockwise, regardless of color). The platforms will move following a circular arc.

After being defeated, the Secret Plant Zone boss will blow up. Eggman then flees in his Egg Mobile, leaving the player to open the capsule and clear the Zone in doing so.
