David and Lisa are summoned to the palace of King Conrad. The king lives behind a waterfall and has a jester named Tim. King Conrad tells the gnomes he wants them to go to the island of Mentoa and find the valuable shadowless stone. The stone is a royal treasure and it is stolen by the trolls. David and Lisa jump down a deep hole, then sail across an eerie red sea. David and Lisa enter Mentoa, a mountain with 1000 steps leading to the top. At the top of the stairs is a chamber holding the stone. Once David picks it up, the trolls materialize out of thin air and chase him and Lisa down the steps.
