From the Super Mario Wiki
Captain Toad must climb to the top of the tower while avoiding the strong wind gusts of Wingo. While climbing the tower, Wingo's wind gusts will move some blocks, which can either help or hinder the player's progress. Once Captain Toad reaches the top of the tower, he will fight Wingo using giant Turnips that fall from the sky. After hitting Wingo three times, he will give up Toadette and a Power Star. Both are then sent flying and land in the treasure, with Toadette having her upper body stuck in it. The player must then pull her out from her lower body to truly rescue her and claim the Power Star of this level.
A hidden 8-bit Luigi can be seen to the left of the HUD while the player is inside the Clear Pipe cannon at the top of the tower.
