This pokemon papercraft is Nincada (Tutinin), a dual-type Bug/Ground Pokémon, based on the anime / game Pokemon, the paper model was created by Odnamra. Nincada evolves into Ninjask starting at level 20. Additionally, if the player has a spare slot in the party and an extra Poké Ball, a Shedinja will appear in the player's party when Nincada evolves. An extra Poké Ball is not necessary to obtain Shedinja in Generation III.
Nincada is a small, whitish insectoid Pokémon. It has a pointed snout, a thin stripe that dips in a V-shaped pattern between its eyes, and whisker-like antennae on its face. The antennae are used to sense its surroundings, as it is virtually blind. Its eyes are black with green iris-like rings inside. Its hind legs are white and the forelegs are brown, and it has small, green wings on its back. It lives underground and builds its nest at the roots of trees. It uses its sharp claws to carve the roots of trees and absorb moisture and nutrients. It does not like sunlight, so it avoids it. [Source: bulbapedia]
