The Hanging Gardens of Mobius was built by Queen Aleena for her own children before they were even born. She intended to show them all the plants of Mobius there, but this plan was thwarted when Dr. Robotnik took power. Robotnik later destroyed the Hanging Gardens of Mobius in his search of the Velocitree, a tree which could grant anyone super speed.
- The Hanging Gardens of Mobius are a reference to the Hanging Gardens of Babylon, one of the Seven Wonders of the Ancient World.
