Tiny Huge Island or THI is the 13th course in the game. There are two variants of the course, the "tiny" one and the "huge" one. In the level are many pipes which take you back and forth between the two. The level is themed around going from one world to another, and interacting with how the size changes affect the world.
There are 2 paintings leading to THI, on the second floor behind a door with a star on it. One is a smaller painting which takes you directly to the tiny version of the course, and the other is a much larger painting that takes you to the huge version of the course.
- Version 1: When a star that isn't Rematch with Koopa the Quick hasn't been selected, Koopa the Quick nor his flag will spawn.
- Version 2: When the star Rematch with Koopa the Quick is selected, Koopa the Quick and his flag will spawn.
There are a total of 192 coins. 34 are in the tiny version, and 158 are in the huge version; 36 out of the 158 are found inside Wiggler's cave. One coin is inaccessible.
