Big Flies are enemies that appear in the Gnat Attackminigame of Mario Paint. They appear after some time of defeating regular Gnats and seem to be upgraded versions of the regular gnats. They are the first enemies to attack Mario; which they do by firing projectiles at him. Mario might want to take them out first.
