Instructions
Approach the enemy you are going to perform the melee knockup attack on. You must be close to the enemy for the attack to connect.
Hold the Wii Remote level to the ground, with the end of the remote pointing at the screen.
Move the Wii Remote side to side four times in succession. Each time you move the Wiimote sideways, Spyro performs an attack. The fourth time is the melee knockup, and Spyro knocks the enemy up into the air.
