The course features three Mini toys.
This level, like Room 7-2, uses solely Color Switches and Polterguys. There are several Pipes, colored blockades and switches throughout the level, and a plentiful amount of Polterguys in scattered small groups. The Minis must time their activating of switches in order to make a path to the Goal Door at the bottom.
Mini Mario Card
The "M" Mini Mario Card is in the top-right corner of the level, beyond some girders and blue Polterguys. A Mini must hit the blue switch at the right time in order to immobilize the blue Polterguys and make a straight path to the card.
