Merlin, a two-year-old duck known throughout Mexico City for wearing the national football team’s colors, has unexpectedly emerged as an unofficial mascot during Mexico’s World Cup campaign. The duck, dressed in a miniature Mexico jersey and socks, gained widespread attention after Mexico’s opening match victory against South Africa on Thursday.

Images and videos capturing Merlin strolling through the city amid World Cup celebrations quickly spread across social media, amassing millions of views. The duck’s sudden popularity has prompted fans to call for Merlin’s presence at stadiums, with some describing the animal as a national treasure and a highlight of the tournament so far.

Merlin had already been a recognized figure in Mexico City’s historic center, regularly accompanying his owner, Carla Gómez, as she sells bottled water and soft drinks from a cart on weekends. The duck’s presence attracts smiles, greetings, and photo requests from locals and tourists alike. Gómez described Merlin as the family’s “baby” and “sole heir” to her possessions, highlighting the strong bond between the duck and her young son, Cristian, to whom Merlin was originally given as a gift. The duck frequently visits well-known city landmarks such as Alameda Central, the Palace of Fine Arts, and the Zócalo square alongside Gómez and Cristian.

“We never imagined he’d become such a sensation,” Gómez said, expressing surprise at Merlin’s rapid rise to internet stardom. The family hopes the duck’s newfound fame will continue to bring good fortune to the Mexican national team as the country participates in its third World Cup as host, this time alongside Canada and the United States.

Mexico is one of three co-hosts of the 2026 tournament, marking its return to the global stage of football events after previous hostings in 1970 and 1986. Gómez concluded by emphasizing Merlin’s enthusiastic support for the team, declaring, “Mexico, we are with you. And Merlin is your No. 1 fan.”
