From Pewter to the Cerulean Gym: Route 3, Mt. Moon and its fossils, Route 4, then Misty.
1 Route 3 and Mt. Moon
Route 3 to the start of Route 4, then Mt. Moon. At the bottom, on B2F, two fossils sit at (13, 7) and (14, 7): they plug the only way to the exit. Taking one (Dome Fossil or Helix Fossil) removes the other (removeobject of both in MtMoon_B2F_EventScript_*Fossil) and sets FLAG_GOT_FOSSIL_FROM_MT_MOON. You leave from B1F onto the east part of Route 4.
