Dugtrio is a set of Diglett triplets sharing a single body, although no one knows what its body looks like since it's perpetually buried underground. Each head is incredibly tough with a smooth surface, and has brown skin, black eyes, and a large, round, pink nose. Dugtrio's three heads think the same thoughts and act cooperatively, though on rare occasions may fight over which head gets to eat first. In order to make burrowing easier, each head will bob up and down to loosen the soil. Dugtrio can tunnel under the earth at 60 mph (100 km/h) to a depth of 60 miles (100 kilometers), triggering tremors and earthquakes. It is capable of burrowing endlessly. Dugtrio lives in tunnels and caves under the earth. Dugtrio is considered important for agriculture as its digging aerates the soil and makes it suitable for farming. As shown in the anime, Dugtrio sometimes lives in hollow trees in forests. It maintains the soil and plants trees to revitalize wooded areas. In Generation II, Fissure was its signature move.
