Cerulean City is a Kanto city reached from Route 4 and Mt. Moon to the west, with Route 24 to the north, Route 9 to the east and Route 5 south toward Saffron. In HGSS a Team Rocket Grunt has stolen the Machine Part from the Power Plant and hidden it inside the Cerulean Gym, while Misty is away at Cerulean Cape on Route 25. Cerulean Cave, home to Mewtwo, is open again after you have beaten all the Kanto Gym Leaders.

Use Headbutt on a tree (taught by the tutor in Ilex Forest). Which trees are “common”, “rare” or empty depends on the last digit of your Trainer ID.

Tips

  • Beat the Team Rocket Grunt on Route 24, then search the Cerulean Gym behind a pile of lifebuoys to find the Machine Part.
  • Returning the Machine Part to the Power Plant restarts it, which gets the Magnet Train running and gives you TM57 Charge Beam from the manager.
  • Misty uses Golduck Lv49, Quagsire Lv49, Lapras Lv52 and Starmie Lv54; Quagsire is immune to Electric moves, so bring a Grass attacker too.
  • Misty’s Cascade Badge comes with TM03 Water Pulse.
  • Cerulean Cave, with Mewtwo at Lv70, opens to Champions who have all 16 Badges.
  • The Bike Shop is open but has nothing to sell, since its bicycles went to Johto.
