More wandering aimlessly around Rolling Ridge finally led me to the Goron Dance Hall. Oh yes. Dancing. Winning the dancing contest thing gained me a Goron Brotherhood badge which lets me go past a Goron guard.
I knew where I needed to go, but there’s a locked door. The owl next to it says something cryptic about a mermaid’s secret, and, since there is a mermaid statue in Lynna City, I went off there. Wild goose chase, it was, as there’s nothing there. It turned out I needed to do a mini swap-a-thon to gain access to a bomb avoiding game. Winning that got me a key. I also had a go at a shooting game, which gained me a boomerand as well as one of the items needed to get to the bomb game.
And now I’m into Dungeon 6 – the Mermaid’s Cave. Tch. Damn cryptic owls.
