Tips
  • When the TunnelBot appears, it causes an earthquake with falling stalactites; avoid these. Other debris is harmless.
  • Wait for the TunnelBot's drills to point upwards before attacking.
  • Due to Knuckles' low jump, you must use the moving spiked platform to hit the TunnelBot mini-boss. Practice this maneuver as it can be challenging.
  • When the scenery sinks, keep moving to avoid being crushed.
  • Quickly hit arrow-shooting machines 3 times to reveal exits.
