The Sand Worm, also known as the SandWorm, is an enemy from Final Fantasy II.
Sand Worm is quick to use the Earthquake X move to inflict Earth damage on the entire party, so beware of that. They can also inflict severe physical damage to a single party member, making them an enemy to watch out for. These monsters tend to appear around Palamecia and Kashuan after the collection of the Ultima Tome, and may be a threat rather than a nuisance if your characters are not up to the basic level to defeat them. This is where the main design of this classic Final Fantasy enemy made its debut.
