Use the Silph Scope to save Mr. Fuji, get the Poke Flute, wake Snorlax, and ride the south/east route chain to Fuchsia. This page is a standalone section for Phase 5: Soul Badge, with source-backed Yellow encounter, trainer, item, hidden item, and boss data.

Route plan

Pokemon Tower is the Ghost/Channeler gauntlet. Routes 12-15 are trainer-heavy and reward careful item sweeps.

Wild Pokemon

Each area below has its own table, split into encounter method bands: tall grass / cave floor, Surfing, the three rods, then gift, trade, prize, and static rows. Grass and Surf rows merge every Gen I wild slot for a species and show the combined odds out of 256 (slot rates 51/256, 51/256, 39/256, 25/256, 25/256, 25/256, 13/256, 13/256, 11/256, and 3/256). Generation I has no time-of-day split, so no rate varies with the clock; a — note means the row needs nothing beyond reaching the area.
