The Animals settle into their new life in the promised land of Diamantina, but all is not well. Diamantina is plagued with earth tremors, one of which causes a rock slide that leaves Gertie trapped in a cave, and after Gorm confesses that Diamantina floods during the night of a full moon, the other animals begin to blame Noah for leading them to a place where they're always in danger. Elsewhere, Chang discovers a cave full of beautiful jewels, but when Ursula finds out about the cave they argue over ownership of the jewels.
