Treasure Cove! is an educational computer game intended to teach children reading and oceanography. The Master of Mischief has caused trouble again. After fleeing Treasure Mountain in the game Treasure Mountain!, he has run off to Invention Island destroying the magical bridge built by the elves. As a result of an awry experiment, he has released goobies, fictional creatures residing beneath the ocean sands, which are polluting the sea. The elves call upon the Super Seeker to collect the gems to rebuild the Rainbow Bridge and stop the goobies. Source: Wikipedia, "Treasure cove", available under the CC-BY-SA License.
