Nincada (Japanese: ツチニン Tutinin) is a dual-type Bug/Ground Pokémon. It 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 insect Pokémon. Nincada's hind legs are white and the forelegs are brown. Nincada has small, green wings on its back, a small pointed snout, and whisker-like antenna on its face. Nincada has a thin stripe that dips in a “V”-shaped pattern between its eyes. It has black eyes with green iris-like rings inside.
