This trick allows you to access Pianta Village without the rocket nozzle. Get behind the Shine Gate in Delfino Plaza, and jump onto the first small wall. Face away from the gate, backflip (quickly press the opposite direction and jump) and hover over to the large Shine, and land on the little overhang surrounding it. Go to the edge facing the rest of the plaza, turn around, and do a triple jump, only make the first two jumps small. Do this next part quickly and carefully: on the peak of the third jump, hover, turn around, and grab on to the top of the gate. Jump into the pipe, and congrats! You've just gotten into Pianta Village without using the Rocket Nozzle.
