Skyward Sword

This scorpion will guard with its claws, but when it opens up to prepare an attack, slash at the eyes in the direction that the claws aren't guarding (so, if the claw opens vertically, slash horizontally)

One eye will turn red. That signifies that that claw will lunge at you and attempt to grab you. If it grabs you, break free by shaking the Wii Remote and Nunchuk.

Once a claw has been hit enough, it will fall off. Do the same to the other claw and the target will change to its head. It will now change its attack strategy to jabbing with its stinger or ramming with its head. When charging the jab attack, its eye will turn red, signifying the weakness. Stabbing its eye will hurt it. If it does manage to successfully charge, a side-jump or backflip is enough to successfully dodge.
