The Deep Dusk Forest (Japanese: もりのたかだい Forest Hill) is the continuation of Dusk Forest in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness and Pokémon Mystery Dungeon: Explorers of Sky. Grovyle and Celebi will accompany the player as they locate the Passage of Time that will bring them back to the past. It has a total of 12 floors. Since this dungeon exists in the future, no Pokémon will be recruited and it cannot be visited again.
Along the way though this dungeon, players will encounter as many traps as they did in Dusk Forest.
