This zone is from a beloved sonic game called sonic CD and it goes by the name "Tidal Tempest Zone" The only thing I like about this zone is the past stage.

Manual Description: As you dive into this underwater adventure, remember that you'll need air once in a while. If you go too long without it, a countdown appears. When the countdown reaches zero, you lose a Life.

Take a deep breath from air bubbles that drift up from certain blocks. Switches activate propellers, and the current will send you spinning. Grab onto the nearest pole to save yourself from steel spikes!
