Cagey Conkdor Caper
From the Super Mario Wiki
Toadette starts on a platform with four Conkdors. After passing through them, she will be at the bottom of the course. There are two yellow Pipes, each taking her to a different part to the top of the course. The one that takes Toadette to a spinning cog, which leads to a lever that raises the railing the four Conkdors are standing from the starting area. After that, Toadette can go on a clear, spinning cylinder, where she can go inside of it and get the Power Star just outside of the cog.
There is a Gold Mushroom on the green platform slightly above the Power Star, accessible by rolling the spinning cylinder to the other end of the stage before walking out of it.
The Pixel Toad is at the wall beside the long rotating cylinder, viewable after rotating it out of the way.
