Nincada

Nincada (Japanese: ツチニン Tutinin) is a dual-type Bug/Ground Pokémon introduced in Generation III.

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.
