New Super Mario Bros. Wii World 4-Castle: Mini Mushroom

This video shows how to clear World 4-Castle of New Super Mario Bros. Wii with only a Mini Mushroom. Sneak around every enemy and hazard throughout the castle while obtaining the Star Coins, and battle Wendy O. Koopa precisely at the end. Good luck! Side note: You have to admit the flooding animation throughout Wendy O. Koopa's rematch is awesome, since it is so colorful and epic. I hope you are having fun enjoying these videos! :)
