The course features three mini toys.
All three minis start in the bottom left corner of the course; two on either side of a Ladder and the third at the top of it. The Goal Door is located at the top on the same side of the level. Guided with Pink Blocks, the minis have to climb up Ladders and bounce off various springs in order to reach the door.
Mini Mario Card
The Mini Mario Card is on the right side of the course, at the top. From their starting area, the minis must climb to the third level and, using Pink Blocks, traverse the spike pit and a Thwomp that separate the two sides of the course. Once on the right side, they will climb a Ladder that leads to the Mini Mario Card.
