The Fireflies resemble fire-red mosquitos with a large head and cartoonish eyes.
The Fireflies are encountered exclusively in Volcano Valley Zone. In gameplay, they will buzz around a set point in an erratic manner. They have no active defensive or offensive techniques; the only way these Badniks can hurt Sonic is if the hedgehog bumps right into them.
- ↑ This Badnik was given no official name upon or after the release of Sonic 3D Blast. However, its name was revealed in the Debug Mode for the unofficial Sonic 3D Blast: Director's Cut video game developed by Jon Burton, the lead programmer of the Genesis version of Sonic 3D Blast. When asked about its validity, Burton that this Badnik's name was used in the original game.
