Yup. Tanooki Suit REALLY Helps in this level. Used it for Peach, but for Rosalina, had it as a back-up, but ended up not using it when I finally cleared it. Cleared it as Super Rosalina, and didn't take damage! (That's a first.) For Mario, Luigi, and Toad, I WILL use the Tanooki Suit....especially at the "Beap Block" section.
