Dunsparce are pale yellow, serpentine Pokémon with two small, white-colored wings that are capable of lifting the Pokémon a few inches off the ground. They also possess a drill on the end of their tail, which resembles a rattlesnake's rattle, and is used for digging. Besides their main pale yellow coloration, they have accentuations of blue, such as the ring patterning encircling their eyes, the thick stripes on the pattern on their back, and their underside. They also have beige accentuations, such as their eyelids and back. Dunsparce's eyes seem perpetually closed and goggle-like in appearance, and there are pointed prongs on the underside of their chin.
At first glance, these Pokémon appear plain. However, Dunsparce make themselves quite elusive.
They also are able to dig extremely well and fly a little using their small wings.
Dunsparce are extremely shy of human beings and rarely ever make themselves known. However, they are known to swarm on random occasions.
Dunsparce prefer to live in caves, forests, and large wide open spaces.
This Pokémon was unavailable prior to Generation I.
