Corrected entry: In several shots throughout the show, there are trees visible. The North Pole is not on any land mass: therefore, there can be no trees.

Correction: There are no flying reindeer in the North Pole either. Nor is there an abominable snowman or an Island of Misfit Toys. This is a fictionalised version of the North Pole which has trees.

Correction: Yukon is clearly not the smartest man on earth. It's a joke, not a mistake, that he's looking for gold in a place where he'll never find it. At most it's just a character mistake.
