Open Pass (Japanese: ジョバンとうげBeginning Ridge) is a playable dungeon the player goes through in Pokémon Super Mystery Dungeon. During the first visit at the beginning of the game, Nuzleaf will mentor the player about the basics of the game's dungeon mechanics on the dungeon's first floor while trying to escape from a pack of Beheeyem. Starting at the second floor, the player will be given control. Only two of the dungeon's floors are accessed on the first visit; the complete trip of four floors can be made on the second visit and onwards.
Because this is the first dungeon of the game that the player and Nuzleaf go through to escape the Beheeyem, there are no traps on either of the two floors. Therefore, only Wonder Tiles can be found here.
