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, insectoid Pokémon. It has a pointed snout, a thin stripe that dips in a V-shaped pattern between its eyes, and two whisker-like antennae on its face. Its eyes are black with green, iris-like rings inside. As it is virtually blind, it uses its antennae to sense its surroundings. On its back is a pair of small, green wings. Its hind legs are white, but the forelegs are brown and have sharp claws. The claws are used to carve the roots of tree and absorb moisture and nutrients. Nincada builds underground nests at the roots of trees. It does not like sunlight, so it avoids it.
