Level 1-mm is the seventh level of Mario Toy Company in Mario vs. Donkey Kong, and is the first level where the player has to lead six Mini-Marios to the toy box. The high score for this level is 15000. This level's time is 90 seconds.
The level starts with a cinematic showing Mario leading the Mini-Marios to collect the T-O-Y Letters and into the toy box, followed by picking the toy box up once all the Mini-Marios are inside. Two Toads then start the level by tossing the toy box into the air, causing it to drop the Letters upon landing.
The player starts with six Mini-Marios following them. To the right, the player has to climb the ladder and lead the Mini-Marios into the T letter, then jump onto the yellow Color Switch ahead, which will cause a Trash Can to fall and create a platform for the Mini-Marios to jump on and reunite with the player. To the left, the player has to climb another ladder and lead the Mini-Marios into the O letter, followed by pressing the red Color Switch to cause the Mini-Marios to fall onto a Conveyor Belt and collect the Y letter. With all the letters collected, the toy box will open and the Mini-Marios will start hopping into it. Picking it up will end the level and the Mini-Marios collected will be turned into the player's damage counter for the fight against Donkey Kong, which will immediately begin.
