The course features three mini toys.
One mini starts on a ledge on the right while the other two minis starts further to the left, on the bottom. The course contains a set of Magnets and Pink Blocks the minis can use to advance to the Goal Door, located towards the bottom left. The player should also occasionally flip some Magnet Rods to help the minis remain on the track.
Mini Mario Card
The Mini Mario Card is on a short platform in the top right. The player can use several Pink Blocks to connect the nearby Magnet to the platform, leading the mini toys to the card.
