We all remember as kids that at some restaurants they had those paper placemats featuring a large drawing with a list of items below it that could be found hidden within. FishDom H2O: Hidden Odyssey is an underwater-based interactive version of your favourite placemat activity that has a cool payoff: The chance to create the ultimate aquarium.

Players assume the part of Jennifer an aspiring Marine Biologist who is looking for a job. Her grandfather encourages her to impress a local aquarium operator by creating an aquarium of her own. Building an aquarium costs money so Jennifer employs her famous oceanographer-grandfather Jack’s suggestion and goes scuba diving on the bottom of the ocean for valuable “junk” that she can sell. The money is used to buy fish and equipment for the aquariums Jennifer will have to build.

This is where the placemat comes in. The game has over a number of different underwater locations that are laden with items that have been dropped into the sea from the time of Zeus to just last week. In timed mode the player has three minutes to find ten items. A simple mouse-click on the item will send it to the surface with the monetary value registered in a running tally at the upper-right of the screen.
