The ? Item is presented as a black icon with a white and golden question mark on it.
In Sonic Labyrinth, the ? Item can be obtained from triangles when they assume a formation consisting of three green triangles that are aligned horizontally.
When obtaining the ? Item in gameplay, all visible Badniks on the screen will be destroyed. At the same time, the icon for the ? Item will appear briefly. In addition, the background will briefly flash green and white when obtaining the ? Item. However, even though the ? Item can clear out Badniks, they will quickly respawn.
