Dunsparce / Dudunsparce

Dunsparce is a serpentine, and somewhat insectoid, Pokémon with a primarily yellow body, blue underside, and blue-and-cream-striped back. Its head is round with a wide mouth extending under its jowls and curving up toward the middle of its face. Its chin is blue with two rounded prongs. Its eyes—round and rimmed with blue—are kept closed, revealing its cream-coloured eyelids. On Dunsparce's upper back are two tiny white wings. Its body ends in a drill-like tail.
Dunsparce can float slightly with its wings, which some scientists believe were used to fly in the sky during ancient times. However, it avoids detection and flees when spotted by burrowing into the ground with its tail. It lives immobile in caves and beneath the earth, where it makes maze-like nests. They get along with Diglett and share tunnels with each other. Dunsparce can navigate through its nests without getting lost in the smell of the dirt.

Dudunsparce is a serpentine Pokémon that looks nearly identical to its pre-evolution, Dunsparce. It has the same yellow body with a blue underside and blue and cream stripes on its back. It sports three "prongs" on its blue chin and its eyes are now partially opened up, revealing its two pupilless white-coloured scleras. It has a dark blue spiral pattern on the underside of its first body segment, and its tail has a blue "cap" on it.
The most notable change Dudunsparce has compared to its pre-evolution is that its body is longer, having gained segments that are similar to Dunsparce's original body. According to a study, Dudunsparce's number of segments is determined by its genes. Each segment has its own pair of wings and back pattern. Two-Segment Form Dudunsparce has two pairs of body segments, with two blue stripes and a pair of two-feathered wings on the first body segment, and one blue stripe and a pair of one-feathered wings on the second. Some Dudunsparce have the Three-Segment Form instead, which has an additional body segment after the head; this segment has three blue stripes and a pair of three-feathered wings.
Dudunsparce is able to use its hardtail to bore holes into bedrock deep underground. Their nests can reach over six miles (10 km) long. It drives enemies out of its nest by inhaling air with its long, narrow lungs, and then releasing it in an intense blast. It is also known to be gentle, however, and will carry Pokémon wandering into its nest on its back and guide them outside.
