Instructions
Complete the 10th mission in the story mode. The Foggy Forest mission must be completed before special missions can be unlocked. Pokemon found inside the Foggy Forest include Pinsir, Dunsparce and Pachirisu.
Recycle items at the Recycle Shop inside Spinda's Cafe. New mystery dungeons become available after the player has recycled 3, 25, 60, 100 and 150 items. Items are recycled by talking to the Pokemon behind the counter and selecting items to recycle in exchange for the opportunity to buy exotic items. Example dungeons earned by recycling include Tiny Meadow and Zero Island Center.
Earn the "Secret" rank for a wider range of dungeon missions to become available at Spinda's Cafe. The "Secret" rank is awarded after the main storyline has been completed and Scizor has been saved from the Crevice Cave dungeon. Return to Spinda's Cafe, and talk to the random Pokemon standing to the left of the entrance to start the latest special missions.
Enter a Wonder Mail code from the main menu of "Pokemon Mystery Dungeon: Explorers of Sky" to open up new dungeons. Select the "Wonder Mail" option before starting your saved file and enter the 34-digit code to open the new dungeon in your saved game. An example is Swinub's "I'm Scared" mission, which is unlocked via Wonder Mail after the following code has been entered: P49P# +HT1M4X C2%HR 3CCQY 9--75JC @&3=@.
