A baby monkey named Yuji became an unexpected viral sensation on social media. He was nicknamed the “Mexican Punch” after his story began circulating online due to its striking similarity to another well-known case involving a baby monkey in Japan.

Yuji lives at the Guadalajara Zoo in Mexico and belongs to the species Erythrocebus patas, commonly known as the patas monkey. Yuji was born in early 2026 at the Guadalajara Zoo.

Like Yuji, he was raised with human assistance and used a stuffed animal as emotional support during early development.

His mother, Kamaria, was a first-time mother and did not know how to properly care for him. She struggled with feeding and basic maternal care, which quickly alerted the zoo’s specialists. In order to protect his health and survival, the veterinary team intervened and placed Yuji under human care.

He was moved to the Center for Comprehensive Animal Medicine and Welfare (CIMBA), where he receives specialized feeding and constant monitoring from veterinarians and animal care experts. Since then, he has been raised under controlled supervision to ensure he develops safely and receives the care he could not get from his mother.

One of the most emotional aspects of Yuji’s story is his attachment to a stuffed animal. He clings to a small teddy bear that provides him with comfort and a sense of security. This behavior has been widely shared online because it closely resembles what happened in another viral case involving a baby monkey in Japan.

The comparison comes from a Japanese macaque nicknamed “Punch,” born in July 2025 at the Ichikawa Zoo. Punch became famous after being rejected by his mother and forming a strong attachment to a plush orangutan toy.

Like Yuji, he was raised with human assistance and used a stuffed animal as emotional support during early development. Because of these similarities, maternal rejection, human-assisted care, and attachment to plush toys, social media users began calling Yuji the “Mexican Punch” or “Punch tapatío,” linking him symbolically to the Japanese case that had previously gone viral.

Despite the comparisons, there are important differences between the two animals. Punch is a Japanese macaque, while Yuji is a patas monkey, a species native to Africa and currently considered near threatened in the wild.

This adds an additional conservation context to Yuji’s situation, highlighting the importance of specialized care and protection for his species.

Today, Yuji continues to receive dedicated attention from veterinary staff at the Guadalajara Zoo. His story has gained widespread attention not only because of its emotional elements, but also because it raises broader discussions about animal care, maternal behavior in primates, and the role of human intervention in zoo environments.
