Instructions
Choose one Scorpion that is by itself and move in on it with the Wii nunchuk.
Perform the Melee Knockup attack by shaking your Wiimote from left to right several times.
Quickly move to the other creature while the first is stunned and repeat the hit-and-run maneuver.
Repeat this until one is damaged to the point where it will open its claws and lie flat on the ground. When this occurs, run up to it and perform the Tail Strike attack to finish it by pressing the "A" button twice, then pitching the Wiimote sharply forward.
