Otherwise, since Sonic Adventure, modern Item Boxes were designed to look like ellipsoid glass capsules with a red cap on the top and an icon inside them that identifies the power-up they contain. Even though they were replaced in later games, classic monitor Item Boxes have made appearances in recent games, mostly in those that feature 2.5D gameplay, such as Sonic the Hedgehog 4 and Sonic Mania. In the early games of the series, they took the form of gray and rectangular/cubic computer monitors with the icon of the power-up contained inside shown on said monitors' black screens. The appearance of Item Boxes has changed on several occasions throughout the Sonic series.
