"WarioWare D.I.Y." allows players to design their own minigames, creating their own graphics, music and designing a 'cassette' for them. The game features three sections in its main menu: My House, where the player designs minigames, WarioWare, the tutorial, and My Shop, where the player makes microgame cassettes. When creating the music, the player can sing through the DS's microphone, which the DS then turns them into notes. These notes can then be performed by various instruments such as pig noises.
