In How to Train Your Dragon 2, Snotlout and Fishlegs fight each other for Ruffnut's attention and affection. Their efforts are useless however, as Ruffnut shows no interest in either of them. Despite Ruffnut's attention targeting Eret, both try desperately getting her approval. Both manage to save Ruffnut in the heat of battle, winning her affection, only for her to be ignored in the end in a comedic fashion.
First spawned from fanart and fanfiction, this pairing involves Ruffnut and Fishlegs as a couple, or at least good friends. This pairing is usually present during a story focusing on the Hiccstrid pairing.
In the fandom, this relationship is often relegated to the background as a subplot for the characters.
