Sonic the Hedgehog Pocket Adventure
Secret Plant Zone

Next zone >>

Secret Plant Zone is the second Zone of Sonic the Hedgehog Pocket Adventure.


Secret Plant Zone is a remake of Chemical Plant Zone from Sonic the Hedgehog 2 but with many visual tweaks to match the limitations of the Neo Geo Pocket Color. This Zone also includes the iconic Mega Mack.



Secret Plant Zone's gameplay is similar to the gameplay in Chemical Plant Zone from Sonic the Hedgehog 2.


Act 1

Act 2


The boss of Secret Plant Zone is Dr. Robotnik, who floats around in an Egg Mobile-like vehicle with two platforms surrounding him. During this boss battle, Robotnik floats around in the middle of the arena and fires off showers of slow-moving bullets in Sonic's general direction. Standing on one of the hovering platforms on either side of the machine allows Sonic to reach Robotnik's vulnerable spot. The platforms sway with Sonic weight's however, so leap with caution.

Photo piece locations

Act 1

  1. From the first Start Post, go right through the loop and launch off the ramp. The photo piece will be on the second step of the platform Sonic lands on.
  2. Along the topmost route, go through the two loops and hop into the high-speed warp tube. Once out, scale the moving platforms and then go into the next high-speed warp tube. Then, just use the spring covering the other side to be launched up to the photo piece.
  3. Follow the first blue path at the start, let Sonic get launched into the air at the end, and land on the right.
  4. Go through the high-speed warp tube on the left of the last photo piece, then hop down the right ledge and continue along the path until the yellow Spring appears. Bounce on it and go past the Spiny.
  5. From the third photo piece, hop left off the ledge and head to the right through the Booster. Go then down the first high-speed warp tube and hold right once Sonic comes out of the other end.

Act 2

  1. Immediatly after the first blue path, use the red Springs to land on the upper platforms. Jump then to the left, across the gap.
  2. From the last photo piece, go back to the red Spring and use it to head upward to the right. Then, Spin through the Spiny, ride then the rotating platforms up and go the the right.
  3. Past the first Start Post, jump off the rotating platforms and hug the left side.
  4. Continue down from the last photo piece, then go all the way to the right until Sonic reaches the high-speed warp tube at the end. Jump then off the ledge to the left.
  5. After the second Start Post, continue along through the loops and go through the high-speed warp tube. Once out, head down to the right, then up using the two moving platforms to reach the upper left area.
  6. Near the end of the Act at the bottom of the Act, there are three sets of clockwise rotating square blocks. Get up on the topmost of these blocks, then walk through the wall on the left.
  7. Past the first Start Post, go down and into the second gap on the right. Continue through the loop, then jump once Sonic reaches the small hill on the blue path. This will launch Sonic up to the right where the photo piece sits.
