Your adventure begins with a complimentary trip to the mysterious Pi'illo Island. After the initial cutscenes and introductions to Starlow and Prince Dreambert, you'll find yourselves in Pi'illo Castle. This introductory segment serves as a tutorial for basic movement and interaction. Follow the on-screen prompts and Starlow's guidance. You'll soon discover the first Pi'illo, which triggers Luigi's unique ability to open portals to the Dream World. This is where the core mechanics of the game truly begin to unfold. Pay attention to the first Dream World tutorial, as it introduces Luiginary Works and the concept of manipulating Luigi's sleeping form to affect the environment. Your first goal will be to rescue the trapped Pi'illo folk and understand the looming threat to the island.

While Mario & Luigi: Dream Team emphasizes turn-based exploration, the game shares its vibrant 3D aesthetic and distinctive character models with the classic Mario Kart DS.
Much like the gravity-defying traversal in Super Mario Galaxy, the initial exploration of Pi'illo Castle introduces players to unique spatial mechanics that redefine standard platforming movements.
