The player starts next to a ladder they have to climb, then move to the right so the Mini-Marios collect the T letter. Heading back, the player has to press the yellow Color Switch to create a platform for the Mini-Marios to jump on, allowing them to collect the O letter, followed by pressing the red Color Switch nearby. The player then needs to head left until the Mini-Marios start jumping up the Springboard below. Next, the player has to use the next Springboard and wait for the Mini-Marios to follow them up. The player then needs to climb and jump from ropes as the Mini-Marios collect the Y letter, and then fall onto the yellow Color Switch to create a path to the Toy Box. Once the Mini-Marios are collected, the player will immediately begin Level 2-DK.
