The Orb is an object that appears in Sonic Dash 2: Sonic Boom. It is a ball used for charging the Dash Bar.
The Orb is a medium-large blue energy orb with a white center that floats in midair.
The Orbs can be found everywhere on the running courses in Sonic Dash 2: Sonic Boom. On ground level and rails, they are arranged in short, and sometimes curving, strings within the lanes. Up in the air along Ener-Rails though, they are set up in more flexible strings to match the more delicate movement options.
In gameplay, the player can pick up Orbs by touching them. When picked up, each Orb fills up a small portion of the Dash Bar. The Sprite Serge however, can increase the size of the Dash Bar the Orbs' fill. Once the Dash Bar is full, the player can initiate the Dash.
