Together, the three go on adventures to protect their citizens of Pure Heart Valley from the forces of evil.
Development[]
After the animated pilot, "I Love You Mao Mao" and the short "I Love You Mao Mao: Bao Bao's Revenge" were finished, it was until a few years later where it was adopted by Cartoon Network to become a series. Before the series started, Parker has posted some shorts and videos about them, including the pilot.

Conception and origins[]
In mid to late 2013, when Parker had spare time he did drawn a couple doodles of three main protagonists, which will be made for a independent short "I Love You Mao Mao", which Simmons had initially produced for the annual Titmouse Inc. "5-Second Night" on February 21, 2014 at 7:30 PM.[1][2] A short were also subsequently posted on Youtube day later[3] and on March 6, that same year at Newgrounds.[4]
Short sparked a lot of interest shortly after release of it (and unlike previous Parker's shorts it got many fanarts online), so Parker and his friends began working on a short, which was later used as a pitch to Cartoon Network. Eventually, finished on November 2, 2015,[5] and shown (once) at the 5 Second Night screening at The Egyptian on February 19, 2016.[6][7][8]
