The player first needs to move to the right and climb down the far right ladder, throwing the two Shy Guys at each other to defeat them. Now the player needs to climb back up and press the blue Color Switch, allowing access to the area on the left with the Mini-Mario. The player needs to both move the Bin out of the way and collect the Mini-Mario, then climb back up the blue ladder. After pressing the red Color Switch, the player needs to move right so the Mini-Mario can jump onto a Springboard and regroup with Mario. Using another Springboard, the player and the Mini-Mario need to reach an upper platform with a blue Color Switch by jumping from the red platforms. By pressing the blue Color Switch, a platform will appear that will allow the Mini-Mario to reach the locked door and open it.
