Volcano Valley Zone Badnik 1
From Sonic Retro
Resembling an evil-looking ladybird, this badnik will trundle around a set area in an erratic manner. It has no active defensive or offensive techniques; the spikes on its back are purely cosmetic, so the only way this bot can hurt Sonic is if the hedgehog bumps right into it. Attack with a spin jump or spin roll. Smash it to recover its organic battery power source, a Flicky, and make Flickies' Island a slightly less dangerous place.
