Nincada is a Bug/Ground-type Pokémon. It evolves into Ninjask at level 20. This evolution can trigger the creation of Shedinja if there is a spare Pokéball in the bag and an open space in the party.
It makes its nest at the roots of a mighty tree. Using its whiskerlike antennae, it probes it surroundings in the pitch-black darkness of soil.
Biology
Physiology
(From Bulbapedia)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.
