Wild Pokémon holding this item

These wild Pokémon can carry King’s Rock. The hold chance is the base chance that the Pokémon has the item when encountered, before Ability effects such as Compound Eyes. The encounter chance shows how often that Pokémon appears for the listed method and time.

Locations are in rough story order for each Pokémon. Radio, swarm and other special encounters require the conditions shown; see the location page for details. Calendar encounters can replace ordinary encounter slots. Safari Zone entries depend on the selected area and, where noted, its objects and their development. “Not fixed” means no fixed encounter chance is listed. Contest weights are shown as weights, not percentages.
