Onion

The Onions are the Pikmin homes. They were originally spacious and comfortable until Olimar came along and designed the new and improved Onions that you can see in the picture. The new Onions are cramped and uncomfortable. They also explode on contact, killing the very few pikmin inside it. The Pikmin once staged a protest outside Olimar's ship. It was about many things, the first of them being the new Onions, but it died down when Louie called in the heavy artillery. The old Onions were actually living creatures until Olimar replaced them with the new ones and banished the spacious Onions to the darkest corners of the Cave of Torture where they are guarded by fire, water, poison and electricity. Olimar likes to take his Pikmin slaves friends to walk through the hazards and while they are burning/drowning/suffocating/being electrocuted Olimar shows them the Onions and laughs.
