The Nintendo DS universe refers to the Smash Bros. series' collection of stages and properties that hail from the default software on Nintendo's Nintendo DS handheld video game system. There are no characters to hail from it, making it one of the three universes without a playable character.
PictoChat: Based off of the PictoChat software built into every Nintendo DS, this stage evokes the whimsical doodling element of the software. While it is, at its base form, a completely flat stage, scenery and new elements are quickly drawn onto the stage and then erased and replaced as quickly as they appear, creating an ever changing battlefield.
