The Soda Seas is an ocean to the southwest of Club Penguin Island, only accessible via the Aqua Grabber. It's the second of the two Aqua Grabber levels, the first being Clam Waters. It is an area polluted by many barrels of Cream Soda that fell in, making the water purple and the sea anemones unhealthy. It is the home of the Pufferfish that guards the valuable Amethyst found in a cave. To complete the level, penguins must grab soda barrels and put them in the net.

By doing so, the anemones will rise up and allow penguins to reach previously inaccessible areas, before finally encountering the level's Guardian, a Giant Pufferfish, to reach the Amethyst treasure. After collecting four barrels, players can find a Worm by bumping the top of an air pocket situated west of the center of the sea. Dropping a worm into the net will only yield a single coins. However, they are better used as bait, as players may attempt to catch Fluffy the Fish who roams around the center area of the sea. Fluffies will provide a larger sum of coins than the worm, yielding 200 coins. Alternatively, the player can go to the south-east of the sea and try to catch a Mullet with Fluffy. However, Fluffy will try to swim in the opposite direction of the Aqua Grabber and try to ram the machine against the rocks. Once the Mullet is caught, you can let it go and it will swim off, or you can put it into the net for 1,000 extra coins. After going through the tunnel, players will find two paths. One leads upwards to an air pocket, and the other downwards to a crab, a bubble blower, and treasure. Alternatively, by exploiting a design flaw, the player could try to squeeze between the mullet and the wall and tumble their way through to the other side.

Each piece of the treasure near the crab is worth twenty coins, and will appear as a coins. The crab will also try and take some treasure so players should try to be quick. Note that gold can be stolen from the claws of the crab. Players can also let the crab get all of the treasure. If they do this, the crab will give the player the rare treasure: an Emerald. An Emerald is worth 500 coins. Players can also receive a Stamp if they take all of the crab's treasure, although less coins will be earned.
