1 Prof. Jones: So, north then. That most mysterious of directions, full of danger, trepidation, and horrors beyond the ken of man.
2 Monty: Indeed. Lands bound with ice and snow. Vast and hostile landscapes that strip souls to the bone.
3 Monty: The howling winds of the Wendigo. Trackless and cyclopean wastes populated only by wolves, bears, and worse.
4 Prof. Jones: Actually, I was talking about lutefisk.

Yes, I know they're going to northern Germany, and lutefisk is a Scandinavian thing, and, even more egregiously, the wendigo is an Algonquian legend of northern America, so they're almost certainly not in any danger of encountering either of those on their current travels.

But I couldn't think of anything from northern Germany that was nearly so mind-numbingly horrifying as lutefisk.
