Sonic the Hedgehog Pocket Adventure

In Sonic the Hedgehog Pocket Adventure, Dr. Eggman used this vehicle to attack Sonic when he was passing through Secret Plant Zone. In spite of Eggman's efforts though, his vehicle got destroyed by Sonic in the end.


The Secret Plant Zone boss is the second boss of Sonic the Hedgehog Pocket Adventure. The player fights it at the end of Secret Plant Zone Act 2.

Boss guide

When the player arrives in an empty arena at the end of Secret Plant Zone Act 2, Dr. Eggman will move in from the right side of the screen in his vehicle until he is in the center of the arena. He will then deploy the red and blue platforms with spikes underneath them, which will position themselves on each side of Eggman's vehicle, initiating the boss battle. During the battle, Eggman floats around in the middle of the arena and fires showers of slow-moving red bullets in Sonic's general direction.

To defeat this boss, the player has to hit Eggman eight times. Since Eggman cannot be reached from the ground however, the player must use the spiked platforms that float next to Eggman to set off from and reach him. However, the player has to watch out for the spikes on the bottom of the plaforms and the red bullets that Eggman fires when trying to reach the plaforms. Also, when reaching one platform, the player will cause the plaform they stand on to move around Eggman in a downward circular arc (until it reaches the lowest point) while the other platform moves above Eggman in an equally upward circular arc. As such, the player has to be quick to jump off the plaforms in order to reach Eggman.

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.
