This video shows how to clear World 7-3 of New Super Mario Bros. Wii with the Ice Flower. Freeze any Fuzzies and Big Fuzzies to stop them from damaging you while claiming the Star Coins, and keep your guard up as you use the Mushroom Platforms and rail-riding lifts to navigate your way to the goal. Good luck! Side note: If you thought 7-3 was hard, then the next level, 7-4, is also hard. I will be working on the first six videos of 7-4 carefully next week, and the first three 7-4 videos will be uploaded on Monday, October 27, 2025, so please stay tuned.
