Ambling Bellows is a mark in Final Fantasy XIII, found in Taejin's Tower, as part of Mission 22, Mission 18 and Mission 10. Similar to the related Boxed Phalanx enemy, it can call and power up the Cryptos, and is a formidable foe on its own as well. It will call more Cryptoses if they are all destroyed, but will not if one still remains.
