It does, doesn't it? Specifically, Final Fantasy VI (III, for the initial North American release.)
Zone Eaters were fun to level off of once you got a party tough enough to take one down before they all got eaten. Plus, since "Engulf" is its most common attack (its only other attack being a rather anemic physical strike), and doesn't result in immediate "Game Over" if all your party members get vacuumed in, they were relatively safe to fight.
(BTW, catgirl is Pendragon's, since he was first to guess it.)
