Burmy

Burmy (Japanese: ミノムッチ Minomucchi) is a -Type Pokémon introduced in the Generation IV.

Evolution
Burmy can evolve into either Mothim (male) or Wormadam (female) once it reaches level 20.

Game Info
Its cloak is based on what location it most recently battled in. If it battled in a grassy area, it will have the grass cloak. If it battled at a beach or in a cave, it will have the sandy cloak. If it fought in a building, it will have the trash cloak. Once a (female) Burmy evolves into Wormadam, its cloak becomes part of its skin, and decides the Wormadam's second type.

Trivia

 * Burmy and Wormadam share the same species name with Pineco and Forretress. They are all known as Bagworm Pokémon.
