Ruffnut is both the recipient and giver of romantic interests with several male characters in the How to Train Your Dragon Franchise. As yet, none of these relationships have resulted in a stable or permanent connection.
In the seasonal player quest, "That Time of Year, Part II", the player shows Eret the kinds of activities Hooligans partake in during the Snoggletog season. One game-exclusive activity is "Loki's Maze of Cheer", a maze-like obstacle course constructed by Ruffnut and Tuffnut. Instead of acting stand-off-ish when Ruffnut offers to show him the maze, Eret accepts the invitation. Ruffnut exclaims "Whoo-hoo! Mama's going to follow Eret son of Eret down into the maze, my friend, and watch him brave the challenges of Loki."
