“Duh, huh huh...”

—Mokura, Super Mario RPG: Legend of the Seven Stars

Mokura (also known as Mokuka) is a mysterious green gaseous entity that lives in the desert at Land's End. When engaged in battle, Mokura resembles a green cloud with two eyes and a mouth. However, outside of battle, Mokura resembles a small white puff of smoke. When in this form, Mokura wanders around the desert, randomly appearing in different areas and running away from attackers. If an adventurer can chase down Mokura, a battle will begin.

When the battle begins, Mokura will be invisible and assume the name Formless. Since Mokura is invisible, the creature can dodge all regular attacks. Fortunately, Formless cannot dodge special attacks. Since Formless has no magic defense and low HP, it can be taken down with the simplest special attacks. Mokura is master of magic and can use a variety of magical attacks, including Bolt, Static E!, Electroshock, and Solidify. Once a special attack is used against Formless, the cloud creature will assume its true form, the green Mokura. Unfortunately, Mokura will retain all of its powerful magic attacks it used during its Formless state. Fortunately, in his gaseous state, Mokura will be weak against regular attacks (however, the creature will be strong against special attacks). After defeating Mokura, the winning party will earn thirty Experience Points.

Strangely, boss music plays in the background during a battle with Mokura. Interestingly, Bowser will summon a creature that looks like Mokura when he uses his Poison Gas attack. It is unknown if this creature's true name is "Mokura" or "Mokuka". Both names appear in the game, so both names are acceptable.
