Collectibles and completion
Optional discoveries, useful collections and completion goals in Pokémon HeartGold / SoulSilver.
Spoiler notice: This guide discusses story progression or late-game content.
Nintendo DS remakes; version-exclusive encounters differ between HeartGold and SoulSilver.
Two-region Pokédex journey
Track Johto and Kanto encounters by area and method. Record evolutions, trades and version exclusives separately so ordinary route searches do not become fruitless repetition.
Apricorns and special balls
Revisit Apricorn trees and take the harvest to Kurt. These balls have specialised catching uses, making the collection useful as well as decorative.
Badges and optional encounters
The badge journey continues beyond Johto. Keep optional legendary encounters and the final challenge against Red on a separate checklist from the main League clear.
Use the edition note above when comparing a checklist with another release. Story completion, collecting and platform achievements are separate goals.
