Possibly the hardest part of this level is the Tap-Tap egg shot. You want to jump towards the left side of the second platform (the one just below the red star flower), and start aiming an egg during that jump. You want to aim the egg just long enough for the aiming cursor to travel a few blips up, and then release as you're landing on the platform. Hold right the entire time, including to fall onto the stone area where the tap-tap was. Jump on this stone area to travel over the tap-tap.
