'A predatory Krell, which inhabits a cave under this vessel, has stolen the Skull of Salt,' explains the Sprite. 'This is our most precious relic, given to us by Father Sea, which, by its magic, keeps the sea and fresh waters of the world separate. We must have it back.' The Sprites give you a magic potion which enables you to stay underwater without needing to breathe, and then show you to the Krell's cave beneath the wreck. The entrance tunnel descends vertically into the sea-bed. Swimming down, you notice that the walls are heavily pocked with wide, deep holes. Will you continue swimming down into the cave (turn to 105), or stop for a moment to look in one of the holes (turn to 89)?
I love how matter-of-fact that is. Oh yeah, just a potion to let me breathe underwater. Ta for that. Cheerio then!
