Slapping the G string?

[PainInTheBass]

I've only recently discovered RHCP's Return of the Dream Canteen, and been trying to learn the opening few bars of slap on Tippa My Tongue. I've seen various videos of people when they get to the notes on the G string either play P P P or P S P. Is there a right way to play these notes? I'm not studied enough on Flea's technique to know how he would approach this. I've watched the one live video I could find but as always the camera folks don't know how to aim at a fretboard for any length of time to satisfy us musos.
