Wild Pokemon

Version
Time

Each area below has its own table, split by encounter method. Standard rows merge every source slot for a species and are shown per Gen II time window: morning 04:00-09:59, day 10:00-17:59, night 18:00-03:59. A rate spanning all three columns applies at any time; "—" means that species is absent in that window. Phone swarms temporarily replace the normal grass or Surf table, Rock Smash rows need cracked rocks broken, and Headbutt rows use the map's common/rare tree sets. Underlying slot odds: grass and cave 30/30/20/10/5/4/1; Surf 60/30/10; rod odds come from each fishing group's cumulative bite thresholds; Headbutt and Rock Smash odds are direct source percentages.
