Barbie: Ocean Discovery

Take control of Barbie, a marine biologist, as she explores an underwater world full of mini-games and activities to complete her quest and assemble the final treasure map. Guide her through 9 different maps collecting puzzle pieces along the way by finishing various mini-games such as a pong type game, a puzzle slider, a Kaboom style cannonball catcher and more. Interact with the various aquatic life in the maps and watch them swim around in interesting patterns.
