This harsh winter, Hiccup the Bloodthirsty Karasius III is set to travel through the frost to the Heroic Expedition. He has no choice: his friend is dying, and only… potatoes can save him. This mysterious vegetable was brought from America by the father of Norbert the Mad, but Norbert is unlikely to agree to help—he has a score to settle with Hiccup. Or rather, with an ax. But no worries: even if Hiccup isn’t exactly a strongman, he will always find a way to outsmart a dragon and rid everyone of the curse!
