Damn. Caught me. I was honestly thinking everyone would just gloss over that.
At the time I typed that, I was thinking of the other stones as well, trying to remember them all.
Trust me, I know them by heart. I meant to type Sapphire, but somehow it came out a mixture of Zora's Sapphire and Kokiri`s Emerald... At least the Goron`s Ruby didn`t get all mixed up in there somehow.
