In the bustling urban sprawl surrounding the famed Metro City Zoo, a young and eager zookeeper named Charlie discovers a mysterious sample of baboon scat at a glamorous zoo fundraiser at midnight. Intrigued and bewildered by the unique genetic markers in the sample, Charlie vows to find the baboon it belongs to, believing it to be a key to revolutionary conservation techniques.
Our Cinderella is not a young woman but a baboon named Bella, known for her unusually intelligent and mischievous antics within the zoo. Bella’s life is under the tyrannical rule of her domineering troop leader, Brutus, who hoards food and privileges from her. Unbeknownst to all, Bella’s only friends, the gigantic fairy god-monsters—King Kong and Godzilla—watch over her from their hidden lairs within the zoo.
As the zoo’s grand event approaches, Bella longs to explore the zoo grounds, which are transformed into a spectacular banquet under the stars. Seeing her distress, King Kong and Godzilla decide to help her escape her enclosure for the night with a few magical (and monstrously large) manipulations of the zoo’s security systems and enclosures.
The night of the fundraiser, Bella, adorned with a dazzling display of lights (courtesy of Godzilla’s radioactive touch) and a crown of bananas (courtesy of King Kong’s towering reach), sneaks into the party. Her presence goes unnoticed, except by Charlie, who spots her unique markings and behavior but loses her in the crowd as the clock strikes midnight, leaving behind only the mysterious scat sample.
In his quest to find the “Cinderella Baboon,” Charlie faces humorous setbacks and challenges. He navigates wacky traps set by Brutus to deter him, receives unlikely help from a gossiping parrot who wants in on the action, and even stumbles into a cameo by Andre the Giant, who is visiting the zoo and mistakenly thinks Charlie is pursuing a wrestling career.
The search culminates in a suspenseful and comedic showdown where Charlie confronts Brutus, armed with nothing but a banana and his wits. Just as Brutus is about to overpower him, Bella steps in, aided by a tag-team assist from King Kong and Godzilla, who reveal themselves in dramatic fashion.
The twist ending comes when Bella, instead of bonding with Charlie, chooses to lead her troop with the support of her fairy god-monsters. Charlie, initially disappointed, realizes the importance of letting Bella choose her own path. He uses his findings not to capture or control, but to advocate for better living conditions for the zoo animals, turning the zoo into a conservation-focused sanctuary.
Bella becomes a symbol of empowerment and change, King Kong and Godzilla are revered as guardian legends, and Charlie continues to work, now with a greater respect for the animals as individuals, not just creatures under his care.
