Pearls are hidden inside four of the five clams in Clam Waters. The player has to wait several seconds by a clam for them to fall asleep, then grab the pearl. Each are worth 25 coins.
The black pearl is in one of the clams in Clam Waters. Which clam has this pearl is random every time the level is entered. It is worth 50 coins.
The pearl shaped rock is in a cavern at the bottom of Clam Waters. It is meant to be dropped in the giant clam's mouth so the grand pearl can be retrieved without waking the clam up. If it is dropped in the net, it is worth 1 coin, and the level is counted as cleared, although no objectives in the menu can be completed by clearing it this way.
The grand pearl is in the giant clam's mouth in Clam Waters. If the pearl shaped rock is dropped in the clam's mouth, the pearl can be retrieved. If it is dropped in the net, it is worth 300 coins, and the level is cleared.
Cream soda barrels are scattered throughout Soda Seas, polluting the water and damaging ocean life. If they are dropped in the net, they are worth 50 coins each. Every time a barrel is dropped in the net, some of the soda pollution is cleared, and ocean life, such as seaweed and coral, is healed, which allows progress in the level.
The amethyst is in a cavern deep in Soda Seas, beyond other caves with puffer fish, including a giant one. If it is dropped in the net, it is worth 600 coins, and the level is cleared.
The coin pile is hidden in a cavern beyond the mullet in Soda Seas. A crab nearby tries to take the coins. The pile can be grabbed up to ten times, by the player and/or the crab. Each time it is grabbed from, it yields 20 coins, for a maximum of 200.
The emerald is given to the player by the crab in Soda Seas if it is allowed to have all the coins in the pile. If the pile is grabbed at all by the player, the crab does not give up the emerald. It is worth 500 coins.
There are five clams in Clam Waters, each of which has a pearl. Four of these are regular pearls, one is a rare black pearl.
The giant clam is at the bottom of Clam Waters, and holds the grand pearl. If the pearl is grabbed from it, it will eat the player and spit them out. If the pearl shaped rock is dropped in its mouth, it will not wake up if the pearl is grabbed.
A fluffy swims around near where the giant clam is located in Clam Waters. Two more appear higher in the level once the grand pearl is grabbed. Another fluffy swims around the central area of Soda Seas. If the player has the bait, this fluffy can be grabbed, but it will struggle and move around every few seconds. It can also be used to catch the mullet. If it is dropped in the net, it is worth 200 coins.
A mullet swims around at the entrance to the bottom caverns in Clam Waters once the grand pearl is grabbed. Another appears in a cavern in the east side of Soda Seas. Beyond this mullet is a hidden cavern with a pile of coins and a crab. This mullet can be grabbed if the player has fluffy as bait, but it will struggle forcefully and move around every few seconds. If it is dropped in the net, it is worth 1000 coins. If it escapes once caught, it will not reappear until the level is restarted.
Although it cannot be interacted with, a silhouette of the giant squid can appear in the background Clam Waters. When going near the entrance to the bottom caverns, there is a 5% chance it appears. When this happens, the sea will shake, the giant squid swims around in the background, stays still for a few seconds, then swims away.
The bait is in a cavern in the west side of Soda Seas. The ceiling of the cave has to be bumped into multiple times in quick succession for the bait to drop from the ceiling into the water. The bait can be used to catch fluffy. If it is dropped in the net, it is worth 1 coin.
Three pufferfish appear in a cavern deep in Soda Seas. They are initially small, but inflate themselves if the player is near, and deflate if the player leaves the area. Two appear circling around the giant pufferfish after it inflates.
The giant pufferfish is near the bottom of Soda Seas, above the amethyst. If the player is near, it inflates itself, inhaling air in the process, which pulls the player toward it. After several seconds, it deflates, exhaling air, pushing the player away.
The crab is in a hidden cavern beyond the mullet in Soda Seas. It tries to grab coins from a nearby pile and take them into its cave. Each time it grabs some, it moves faster. If it grabs all the coins in the pile, it gives the player a emerald, then retreats into its cave. If any coins are taken from the player, it walks back into its cave, annoyed, and does not give up the emerald.
Clam Waters: Collect all the pearls and the "Main Treasure" (the giant pearl). The Rare Treasure of the level was a black pearl which was hidden in a random clam that changed every time.
Soda Seas: Collect all of the cream soda barrels and the "Main Treasure" (the amethyst crystal). The crystal was guarded by puffer fish. The rare treasure of the level was the emerald, which was guarded by a crab. To get this, you had to let the crab take all of the gold, then it would give you the treasure.

In August 2008, the Soda Seas levels were added.
On July 26, 2010, Aqua Grabber got a major update. The title screen was updated and a progress saving feature was added. New game features such as Time Trial and Compressed Air Mode were added to go along with stamps. The Soda Seas levels were also only made members-only. A bug in the game which made it impossible to find your treasure after you dropped it was also fixed.
