The Zone Eater is an enemy in Final Fantasy VI that only appears on Triangle Island in the World of Ruin. Its only attacks are Gravity, Inhale, and Freezing Dust, thus, it is incapable of killing the party members. The true purpose of the Zone Eater is to recruit the optional character Gogo from inside the monster's stomach. To do this, the player must wait for the Zone Eater to inhale their party members ending the battle when the entire party is eaten and spawning them in the Zone Eater's belly.
Being inhaled has roughly the same effect as the move "Snort", excluding the fact that if all the party members are "absent" (blown-away/inhaled) they'll appear in the Zone Eater's belly, rather than the world map. If a party member is inhaled, and the remaining party members defeat the Zone Eater, the absent party member will still be intact, but will not share in any experience or AP gains. Like Snort, a party member who is KO'd counts as already being absent (this is likely also true of petrified and zombified party members).
