The course features two Mini Donkey Kongs. It is one of the three courses (aside from Room R-8 and Room R-9) that need to be completed in order to unlock the option to replace the minis in most courses with Mini Donkey Kongs.
One Mini Donkey Kong starts in the bottom left, while the other starts on a Magnet right above. The Goal Door is located at the top of the level. To bring the minis to the Goal Door, the player has to use Pink Blocks and Magnet Rods without leading them into Piranha Plants. There are also several Pop-up Gates that can be used to change the direction of the minis.
Mini Mario Card
The Mini Mario Card is in an area at the top right between a Magnet Rod and a wall. When a Mini Donkey Kong reaches this Magnet Rod, the player has to flip the toy to the other side to collect the Mini Mario Card. The player has to flip the Magnet Rod again immediately afterwards to prevent the mini from walking up to a few Piranha Plants on the ceiling.
The M-Token is next to a row of Piranha Plants stuck to the bottom of a platform near the center of the course. A Magnet and a Magnet Rod lead to the token. Immediately after collecting it, the minis have to be flipped to the other side of the Magnet Rod so that they do not walk into the Piranha Plants.
