Spinwheel Library is the 7th course of Episode 1 in Captain Toad: Treasure Tracker. This level takes place in a Ghost House. The player starts next to a Spinwheel, which is used to rotate the center part of the course. The player simply needs to rotate the Spinwheel twice (180 degrees) to reach the course's Power Star.
A hidden 8-bit Rosalina image can be found on one of the books near the purple Warp Pipe. This was removed in the Nintendo 3DS / Nintendo Switch version of the game.
