Whistle to call the storm a mysterious girl! - S1.E6

Living in Mt. Fuji's plentiful forest, Monora was hypnotized by a woman playing a flute. The music seemed to lull the monster into a sluggish state, almost peaceful. It wasn't until Ururu's bellowing roar awoke Monora's rage and he chased the woman out of the forest. Days later, the woman was contacted by the D-Force, who used her flute playing to their advantage, luring the monster out of hiding! Monora seemed to be willingly cooperating with the humans and not even Ururu's massive roars could awaken him! The woman's flute playing allowed for the D-Force to fire a net over the monochroceratop’s body, and as she kept playing, Monora fell asleep! Soon, the woman became aware of what the D-Force was planning, and played a different song on her flute, sending Monora into a rage. Breaking free from his nets, the ceratopsian attacked anything that moved with hellfire.
