"Bad Horsie" horse sound effect

there are two ways to do the guitar effect that makes it sound like a horse wailing.

One way to do it is to do a pinch harmonic (place your thumb on the pick so immediately after you pick the string, your thumb will lightly touch the string) on an un-wrapped string (G, B or e) then bend it very high and slowly release the bend and as your releasing, vibrato with the whammy bar

Another way to do it, which I think sounds much better, is to do a natural harmonic (quickly, lightly touch the string with your fretting hand) near the 2nd fret of the G string, then on the whammy bar, go down, then pull up and vibrato with the whammy bar and as your vibrating, go down on the whammy bar.
