Fishlegs, on the other hand, eats all the berries . Soon they get a stomach ache and return to Berk to get Meatlug checked by Gobber . 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 . </Td> </Tr> <Tr> <Th> 23 </Th> <Td> </Td> <Td> "The Night and the Fury" </Td> <Td> Louie del Carmen </Td> <Td> Jack Thomas </Td> <Td> October 3, 2013 (2013 - 10 - 03) </Td> <Td> 1.09 </Td> </Tr> <Tr> <Td_colspan="7"> The teens are doing a training exercise led by Astrid to their disappointment .
