The course features three Mini Mario toys, one of which is a Key Mini Mario.
The two keyless Mini Marios start in the bottom left, right next to the Goal Door but facing away from it. The Key Mini Mario starts on a platform at the top, but is initially kept away there by several active Polterguys that lie in its path. The player should first use Pink Blocks to guide the keyless Mini Marios to the red and yellow Color Switches found on different platforms in front of them. By pressing these switches, the Polterguys ahead of the Key Mini Mario turn into blocks and become safe to pass. All minis should then be directed to the Goal Door, with the Key Mini Mario in front of the group to reach the door first and unlock it.
Mini Mario Card
The Mini Mario Card is on a platform in the middle right. It is obtainable by guiding the minis there with Pink Blocks, either from the platform with the Yellow Color Switch or from the platform with the M-Token.
The M-Token is located on a platform in the top right, just above the Mini Mario Card. To reach and collect it, the minis have to be guided there with Pink Blocks from the platform containing the Yellow Color Switch.
