DoroDoron  

, ドロドロン,

DoroDoron is a third Dark Fall to attack Earth after Moerumba fails. He's an arachnid-like creature that moves underground instead of through the air. DoroDoron turns earth-related objects like rocks and cobblestones into Uzainaa monsters. Occasionally, he takes commands from two suspicious girls (Kaoru Kiryuu and Michiru Kiryuu) who are in the same class as Mai and Saki. His name comes from "doro," meaning "mud" in Japanese.
