Pokémon Mystery Dungeon: Red Rescue Team Tips

Recruiting Gardevoir
If you've unlocked wish cave and saved Medicham, the next day you wake up, go see Medicham and Ekans at the Pokemon Square. They will say Gengar wants to go to Mt. Freeze. Go do a rescue mission or explore a dungeon, and the next day Gengar will see you. Escort him to Mt Freeze and you will meet Ninetails.Ninetails will tell you to go to Murky Cave (20 floors)and on the bottom, Gengar will be judged. Finally you will all get out and the next day Gardevoir can be recruited.(Gardevoir is lv 5 and her area is Sky Blue Plains)
