Bastian arrives to see that Barktroll has been pleasantly rewarded (with faerie dust) for his efforts when he inadvertently helps a town of Faeries. However, Barktroll soon expects rewards from everyone, including a lonely trekker named Trell, who collects water and delivers it back to his town, where they suffer from drought. The jeopardy begins when Barktroll accidentally leaves the jug cap loose, breaks Trell's cart and water barrel, and ends up having them cornered by nasty Wolvers.
