Eartha

''This article is about the Earth of the All Female Galaxy. For other versions, see Earth (disambiguation).''

Eartha is the name of the planet that Sonica the Hedgehog and Runa the Hedgehog live on in the All Female Galaxy. It is similar to Mobius (Prime Galaxy) but buildings are destroyed, trash is piled up in the streets and sewage is rampant due to no men being around to take the jobs the women didn't want. Runa describes it as a "shit hole."
