My rather incompetent friend has been playing through MM recently, and while in the well to get the Mirror Shield he came across two skulltulas. Instead of patiently waiting he managed to jump attack close enough so that when it did its own spin attack to counter Link's attack, Link wasn't sent flying in the same direction he usually goes.
No, that damn skulltula managed to toss him into his skulltula friend, who also countered with a spin attack. And they had a pleasant time volleying my friend to his death. Gives a whole new meaning to the phrase, Dead Man's Volley.
Mind you, my friend gathered up quite a few heart containers by this point in the game and this cursed volleying carried on THE WHOLE TIME!
This friend of mine has literally had the worst luck playing through any of these Zelda games, dying in really bizarre ways...guess that's why I let him play, haha.
Another one that happened (from recollection) is that instead of pausing the game to look at his phone he just put the controller down. Meanwhile a keese (or maybe it was a fire keese) was flying at him. I'm not sure how, but I guess where my friend was standing was in the same path that the keese was heading so when it ran into him it just kept pushing him slowly back. He didn't look up until he was at the edge of a cliff, but was so dumbfounded that he just watched the keese push him to his death.
