Fishlegs discovers that Meatlug can produce "Gronckle Iron", a lightweight but extremely strong metal. Because their slow speed had previously allowed an Outcast boat to escape, Fishlegs decides that producing Gronckle Iron is a more helpful task than flying with the other teens, until Meatlug ends up ingesting a magnetic rock, attracting all the metal in the village-including Hiccup's metal leg.
