Treasure Cove!

Treasure Cove! is a side-scrolling educational / adventure game whose objective is to plug pipes that are leaking oil into the ocean. The game takes place in the fictional Treasure Cove which is being polluted with byproducts from experiments done by the Master of Mischief, a common antagonist of The Learning Company's Super Seekers games. The player takes on the role of the Super Seeker, whose job is to plug the pipes leaking oil and rebuild the destroyed bridge to the island by finding gems in the cove in order to stop the pollution at its source.

The cove has three separate areas that the player must visit and collect gems to plug the pipes that leak "goobies" by finding the puffer fish and dropping it on the opening. If a player hits a goobie, one light unit is taken from them. To find the puffer fish, the player must gather clues by catching orange starfish and answering their riddles. There are three clues per stage, each a single descriptive term such as "three", "swimming", or "eels". The player must then shine his flashlight on the group of animals that are described by clues to obtain the puffer fish. Shining light on a group of animals that matches two of the three clues will reveal a gem, adding points towards restoring the Rainbow Bridge. After finding gems and plugging leaks in each of the three areas, the player will surface and add the gems collected during the most recent game to the total gem count. When the player has collected a certain number of gems, the player goes up in star rank and the Rainbow Bridge is extended farther. Higher star ranks means that there are more gems to find, the riddles are more difficult, and the fish that steal light move faster and are harder to avoid.
