| Boss Keys | 8, one in every dungeon |
|---|---|
| Small Keys counted | 15 across the five dungeons with a settled count (Gnarled Root 2, Snake’s Remains 3, Poison Moth’s Lair 2, Dancing Dragon 5, Ancient Ruins 3) |

| Game | The Game Boy Color version, Oracle of Seasons |
Every dungeon in Oracle of Seasons holds a Boss Key, which opens the boss door at the end. Maps and Compasses sit in chests inside each dungeon, and Small Keys open the locked doors on the way. The Map shows the layout, and the Compass reveals chests on it. Small Keys work only in the dungeon where you find them. The table below lists where each key item and the dungeon’s main item sit.

A dash means the count or location differs between written guides, or I could not confirm it, so it is left out of the totals.
