Plot[]
Scrooge and the children make it out of a crumbling temple with the Lost Key of Tralla La. After narrowly avoiding an attempt by Flintheart Glomgold to steal it, they escape on a plane piloted by Launchpad, and fly back to Duckburg. There, Donald Duck berates Scrooge for taking the boys adventuring again, which Scrooge denies before diving into his Money Bin.
