Instructions
Run Spyro towards the wall on which you wish to use the wall run.
Press the jump button while Spyro is running towards the wall so that Spyro comes into contact with the wall's surface. The jump button varies based on the system you are playing: press "X" if you are playing on the PlayStation 2 or 3, and press "A" for the Xbox 360 and Wii versions.
Press the grab button and then quickly release it to cause Spyro to attach himself onto the wall, then continue to move Spyro forwards to run along the wall. The grab button on the PlayStation 2 and 3 is "O." Press "B" if you are playing on the Xbox 360. To grab in the Wii version, you must press "A" and "B" at the same time on your control stick.
Press the jump button to detach from the wall.
