Ampilus

The Ampilus is a desert-dwelling, hermit crab-like enemy whose only mode of attack seems to be electrifying its outer shell and rolling at Link. While it resembles a wheel, it appears to be shaped like a spiral or a rolled-up creature, making it somewhat resemble the Rollobites from The Minish Cap. Whether it is simply a wheel-shaped enemy or can unroll and move or attack in other ways is unknown.
