The Item Boxes with Colorball feature a square icon with round corners depicting rippling waves on a purple background.
In gameplay, when the player obtains Colorball, the screen is covered in multi-colored paint in an attempt to distort the player's vision. This effect only lasts for a limited amount of time, however, as the paint will slowly disappear.
The player can obtain Colorball at random times by touching one of the Item Boxes that lie scattered across the racing course. When obtaining it, Colorball's icon appears briefly on-screen.
