Use Shyguy glitch.

Get and use carpet more quickly(8 frames), and save another 3 frames in boss fighter.

1-3 4-1 4-2(0,55)
Copy the input.

Save 7 frames when play the sand, and 2 frames in boss fight.

4 frames of a little far flying. When Peach falling, don't press A at first time, and she will fly a little far, because she will fall twice.
62 frames saved in boss fight. This the biggest improvement in this tas. No need higher jump anymore.

I saved 4 frames before boss fight. Because of the frames rule, I must wait boss fire egg, but I have the enough time to choose the best chance. 2 frames saved after the first boss, and I save another 4 frames

I saved 23 frames when climbing, and 9 frames in boss fight.

I cost more than 30 frames to saved 9 lag frames.

This picture show the biggest improvement.

Masterjun: Judging.

Masterjun: Replaced file with a 48 frame improvement.

Masterjun: Great movie! I love all the small optimizations. Accepting to Moons as an improvement to the previous run.
