Sparkle

Blaster as depicted in the Sonic 3 Manual

The Blaster is a small, grenade-like badnik found in Carnival Night Zone. They are often found in small groups in narrow tunnels, and can hang from the ceilings as well as standing stationery on the floor. After a set amount of time, the Blaster will shoot from one side of the tunnel to the other, emiting two electrical charges as it does so. As long as it isn't travelling or emitting sparks, the Blaster can be defeated by being jumped on, or by using the Spin Dash.
