They are snake bots that have a black and red stripe pattern on their bodies, and a silver horn protruding from their noses. They slither slowly along the ground, but strike with quickness as soon as Sonic crosses their path. Like all Badniks, Sonic simply has to roll into them with a Spin Dash to take them out before they get him.
Their name is derived from "nyoro-nyoro", which is the Japanese onomatopoeia meaning to "slither".
