This enemy is a leaping robotic worm. It spends much of its time underground, but the locations it will pop up are easily identified in the form of two dark pits which it jumps between. Attempting to defeat the badnik with a spin jump while it's in the air may prove difficult; mis-time the leap and Sonic may end up losing his rings (and Flickies) by connecting with the spiked tail. A more cunning method is to charge up a spin dash right on top of the hole; the robot will dive right into the spinning hedgehog and be destroyed, releasing its organic battery power source, a Flicky.
