From Bulbapedia, the community-driven Pokémon encyclopedia.
The Mystery Part and Secret Slab are functionally identical items that appear in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness and Pokémon Mystery Dungeon: Explorers of Sky. When one is in the bag, certain legendary Pokémon will appear on preset dungeon floors. They only appear after the player and their partner have recruited Manaphy and he tells them about the Marine Resort.
The Mystery Part and Secret Slab are obtained as rewards from random missions, such as the one in the following Wonder Mail password:
- X-HY NSM8 6&3&
- 2Q&P 520# 7WQ8
- Objective: Rescue Typhlosion on floor 7 of Treeshroud Forest.
For Explorers of Sky, here is a Wonder Mail S Code:
- [email protected]=X QYC7R9S [email protected]
- [email protected] 5R#6J%8 65NP@
- Objective: Prospect with Rotom on floor 1 of Beach Cave
Note: Rotom also joins the party, however, the player may decline.
Only one of each legendary species can be obtained.
