Pretty sure you gotta use the sinking lure to catch the Hylian LoachI have indeed beaten OoT and MM 100% (I actually went through a run of every game in the Zelda series last year and beat them all 100%.)
MM is one of the hardest in the series to gain 100% because of how steeply challenging some of the Heart Pieces are. But yeah, I got everything.
Between the two games, I think the only thing I've never accomplished is catching the Hylian Loach in OoT. Just...yeah.

I remember my most hated heart container to get, is the one at the end of that mini game in the Market. The one where you have to choose between two chests, one containing a key and the other containing a rupee. I wouldn't mind it too much except for the fact it goes on for like 6 rooms. Took me quite a while to guess all the correct chests
