The course features three Mini Peaches. It is one of the three courses (aside from Room R-4 and Room R-6) that need to be completed in order to unlock the option to replace the minis in most courses with Mini Peaches.
All three toys start in a tight tunnel on the left, facing the entrance into a green Pipe. With the help of a Rotate Pipe, the player must lead the minis to the top. As they walk to the right, the minis will soon jump into a yellow Split Pipe on the ceiling, which warps them to the bottom of the course. In this area, they will soon jump into another green Pipe, from where the player should now adjust the Rotate Pipe to lead the toys to the right. Afterwards, the toys must walk on some Pink Blocks into a wall and change direction, then follow a trail of Coins into the cyan Split Pipe on the bottom and enter it. The toys will be warped further up to the top left, where the player must place some Pink Blocks above a pit of spikes to lead the minis to the Goal Door.
Mini Mario Card
The Mini Mario Card is at the base of a short ledge right under the yellow Split Pipe. After coming out from the right exit of the green Pipe system as described above, the minis should be guided with Pink Blocks further to the top, where they will jump into a magenta Split Pipe in the ceiling. The pipe will warp them to the bottom left corner of the level, from where the minis will follow a trail of Coins to a yellow Split Pipe on the ground and enter it. Soon after coming out of the other yellow Split Pipe at the top, the minis will fall onto the Mini Mario Card and collect it.
The M-Token is inside an alcove in the wall on the right. With the minis coming from the left, the player should place several Pink Blocks that lead to the token to collect it.
