Pure Heart Valley is the main setting of Mao Mao: Heroes of Pure Heart. It is first seen in "I Love You Mao Mao".
Geography
Pure Heart Valley is a heavily-forested region. It is moderately hilly and surrounded by tall mountains.
Pure Heart Kingdom
The Pure Heart Kingdom is home to the Sweetypies, a colorful race of small animals ruled by King Snugglemagne. They are a very friendly and peaceful people, but the majority of them lack any combat skills, and are unable to defend themselves. However, there are Sweetypies who are capable of combat, the most notable example being Adorabat.
Ruby Pure Heart
The Ruby Pure Heart is a gargantuan, heart-shaped crystalline object that sits on top of the kingdom, protecting the Sweetypies with its magical cloaking power. After Mao Mao accidentally crashes into it, the Ruby Pure Heart becomes damaged and no longer functions. This, however, has not deterred Orangusnake, who still attempts to steal it in his quest to rule the world.
