Crevice Cave (Japanese: クレバスのどうくつ Crevice Cave) is a dungeon in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness and Pokémon Mystery Dungeon: Explorers of Sky. It has 14 floors and a relay point between Floor 10 and the first floor of Lower Crevice Cave. It is unlocked after the player completes Blizzard Island. Upon first completing the dungeon the player will battle a Froslass as a boss. After she is defeated, the player rescues Scizor, whom Froslass had frozen and kept for several years. The player then receives the Secret Rank from the grateful explorer.
Darkrai can be found on the second floor of Lower Crevice Cave, but only after Manaphy has told the player about Marine Resort, and if the player has the Mystery Part or Secret Slab in the bag.
