LevelSonic CDLittle Planet
The third round of Sonic CD (1993), Tidal Tempest hides a calm, maze-like sunken temple behind a misleading name, set on Little Planet. No storm here, but submerged ancient ruins and aqueducts, wedged between Collision Chaos and Quartz Quadrant. The danger is drowning: about thirty seconds of air, a numbered countdown on screen and large bubbles to breathe from, without the nerve-wracking jingle of Labyrinth Zone in Sonic 1. Eggman waits there in the Egg Bubble, protected by sixteen bubbles. Time travel sets a turquoise aquarium against a rusted hydraulic plant.
Summary
A sunken temple, an agonizing air count, and a misleading name: Tidal Tempest is the aquatic level in Sonic CD (1993). Despite its name, there's no storm here – just the silence of Little Planet's depths.
🪐 Little Planet and Sonic CD's Time Stones.
🎡 Collision Chaos, the previous level.
Sonic CD's 3rd Zone
Tidal Tempest is Round 3 of Sonic CD (1993), on Little Planet, following Collision Chaos and preceding Quartz Quadrant. It's a system of sunken ancient ruins and aqueducts, calm and labyrinthine — far from the "tempest" its name suggests.
💎 Quartz Quadrant, the next level.

💧 On Little Planet, Tidal Tempest's ancient aqueducts ended up sunken for good; your own water stays right where you left it, in one of our Sonic water bottles tucked at the bottom of your bag.
A Drowning Level… Without Music
Like any aquatic level, Tidal Tempest revolves around drowning. Underwater, Sonic only has about thirty seconds of air; in the final seconds, a numerical countdown (5, 4, 3…) appears on screen. An interesting nuance: unlike Labyrinth Zone in Sonic 1, there is no agonizing drowning music — just this countdown. You breathe thanks to the large bubbles rising from the bottom.

The Bubble Boss
In Zone 3, Eggman awaits you underwater in the Egg Bubble. Its particularity: it protects itself with a shield of sixteen air bubbles and fires small projectiles. An entirely submerged battle that severely tests air management.
Aquarium or Sewer?
Time travel offers a strong contrast here. The Good Future transforms the place into a splendid turquoise and lush aquarium, while the Bad Future reduces it to a rusty and polluted hydraulic installation.

🐠 In the Good Future, Tidal Tempest swaps the Bad Future's rusted pipework for a turquoise and lush aquarium; to change the mood on your bedroom walls, our Sonic decorations spare you the time travel.
Its Reappearances
Tidal Tempest has never been remade as a playable level elsewhere, unlike Stardust Speedway or Metallic Madness. It remains playable in all re-releases of Sonic CD, up to Sonic Origins.
