Meetles are beetle-like creatures that were supposed to appear in Oddworld: Munch's Oddysee. Meetle larvae can be influenced to grow into one of two forms. Meetles that are fed vegetables and plants grow up to be friendly herbivores that can supposedly be herded. If they are fed meat, however, they grow up into carnivorous Mugs, which are used by the Industrialists as war machines.
