Floating Item Box

The Floating Item Box, also referred to as the Balloon or Item Box, is an object that appears in the Sonic the Hedgehog series. It is a variant of the Item Box that resembles a balloon, but otherwise grants power-ups when popped. In other cases, they hide objects inside them.

Description
Design-wise, the Floating Item Boxes (typically) resemble large red balloons with the picture(s) of a blue circle containing a five-pointed yellow star emblazoned on them. Their design also sometimes includes a knot that closes the opening on each balloon's bottom and even a thread dangling from the knots.

In gameplay, Floating Item Boxes can always be found floating around in midair. They can also be popped upon touch with the playable character or when hit by a long-ranged attack. Like when opening regular Item Boxes, popping an Floating Item Box will in most cases result in the player receiving a power-up. However, because the Floating Item Boxes do not display the icon of the power-up they contain until they are popped, the player will not know what to receive until after the Floating Item Boxes are opened. In other cases, the Floating Item Boxes keep things inside them, hidden from view, until they are popped.

Like the Balloon gimmick, when opening a Floating Item Box through physical touch, the player will receive a small aerial boost.
