The Soda Seas is an ocean which can found southwest of Club Penguin. You can access it by playing Aqua Grabber. It is the second level that can be picked, the first being Clam Waters. The water appears purple as it was polluted when a bunch of Cream Soda barrels fell in.
To complete the level, the player must drop the barrels into the net, each giving 50 coins. This will open up new sections of the level and pure the water slightly, eventually leading the player to the Amethyst treasure. There are enemies in the treasure section such as the Giant Pufferfish and numerous small pufferfish which will knock the player across the screen and drop the Amethyst if not avoided.
1: On the left side of the level you will find an air pocket, if you bash it hard enough then a worm will drop. This worm can then be used to catch Fluffy the Fish or alternatively can be dropped into the net for a measly coin. If you catch Fluffy then you can use it as bait to catch the Mullet, or drop it in the net for 200 coins. Choosing to do the mullet will have him fight to try and break free, if you manage to catch it then you will get 1000 coins.
2: Go to the right-hand side of the level where the Mullet is located. Get rid of him then go down the rightmost path. You will find a bubble blower, treasure and a crab, taking the treasure will give you 20 coins for each piece, if you manage to take it all you will get the Crab's Treasure Stamp, however, if you let the crab take all of the treasure then it will give you an Emerald worth 500 coins.
