The thief class predictably makes its way into Chocobo’s Mysterious Dungeon: Toki Wasure No Meikyuu. When he dons the green bandanna, Chocobo can steal and use a few status inflicting attacks. The scholar job is unexpected, but after hearing about the abilities it’s a natural fit. This job boosts the effects of items and lets the Chocobo identify items inside the dungeon.
Also if you played through Final Fantasy Fables: Chocobo Tales you’re bound to recognize more than a few faces. Cid, Volg, Irma, Shirma, and Moogle X are confirmed to be in Chocobo’s Mysterious Dungeon: Toki Wasure No Meikyuu.
