The Jabberwock is an enemy from Final Fantasy IX. It can be found on the Blairsupass Plains on the Forgotten Continent. If anyone has Float, it will remove it with Heavy to ensure that its Earthquake finds its mark. It will also cast Float on its prey with Light and Everyone Light so that its Aera spell will do more damage.
However, it tends to cast Earthquake right after "Everyone Light", making it an easy enemy even with it's high amount of hp (they appear in pairs and have almost the same amount of hp than harder monsters of the same area like Adamantoise and Catoblepas).
The Jabberwock also has a friendly counterpart encountered in Seaways Canyon on the Forgotten Continent as part of a sidequest. It requests the party give it an Emerald, for which it will reward 40 AP and a Moonstone, which should be given to the Feather Circle enemy next.
