Route plan

Do Nugget Bridge before Misty if you want levels and extra catches; the Rival is the real pace check of the phase.

Route Notes

  • The Nugget Bridge Rocket gives the Nugget before the recruitment battle; the robbed house Rocket gives TM28 Dig.

Wild Pokemon

Version

Each area below has its own table, split by encounter method. Standard wild rows merge every slot for a species into one line with a combined rate, and FireRed/LeafGreen exclusives are marked with FR/LG game chips; there is no time-of-day split in these remakes. Underlying slot odds: grass and cave 20/20/10/10/10/10/5/5/4/4/1/1; Surf and Rock Smash 60/30/5/4/1; Old Rod 70/30; Good Rod 60/20/20; Super Rod 40/40/15/4/1. Gift, static, trade, and prize Pokemon keep their own labeled rows.
