The Zoo Hospital is a new game for the Nintendo DS. It's a 2D adventure game with a 3D twist. You're a doctor who has to save the zoo from a dark fate. Your do-or-do-ish approach to healing the zoo turns some of the animals into just fine, Happy. But there's a dark side to this tale. A dark act of evil aliens has left the zoo in disarray, and they're not the only ones to be affected. Your competitors are out of luck, too. You have to help us recover the medallion that's been removed from the hospital. Along the way, you must stop the aliens from using the medallion to start a fire that will destroy the zoo.
