The Tommy Turtle Memorial Hospital is a hospital located in New Mobotropolis that serves as one after the old hospital, the Julayla Memorial Hospital, was bombarded by Dr. Eggman along with the rest of Knothole.
It was named in honor of Tommy Turtle, who willingly sacrificed himself whilst being used as a vessel for Eggman's rogue computer virus, A.D.A.M., when he briefly regained control of his body and allowed himself to be destroyed by the Egg Fleet. (StH #169, #175, #205)
After nearly having been turned into stone by Naugus, Bunnie was placed there. Naugus, by accident, turned Bunnie back to normal, reversing her roboticization. Some time later, Antoine was placed there after Metal Sonic ambushed him in a battle. Silver, coming from the future, claimed to Sonic that Antoine was the traitor that he'd been looking for, but Sonic dragged the time-traveling hedgehog to Antoine's room in the hospital. Silver was proven false and left for the Julayla Memorial Park. (StH #232, #234, #235)
