I did it on Stage 5-1 "Pearl Clam" with the flipper ability. If you get the ability on the first ball it is basically impossible to loose the ball.
Hold the button down so the flippers are up and the ball can't fall through to the bottom. And the pegs don't disappear so just keep flipping it around until you get the 3 point multiplier.
I got it first time after i realised this could happen.
