Merlin did not just turn up in Mexico City's streets wearing a Mexico FIFA World Cup jersey and custom socks. The 2-year-old domesticated duck became a viral World Cup oddity after Mexico won its opening game against South Africa on June 11, and people quickly latched onto the bird as an unlikely flag-bearer for the team.
That is why searches for Merlin are spiking now: the duck became Mexico's biggest fan at the same moment the tournament story line sharpened around Mexico's opening result. Karla Gomez, who said she typically sells drinks in Mexico City's streets with her son Christian and Merlin, described the reaction as a surprise and said people have embraced the duck as an unofficial mascot.
Gomez said, “For us it has been a surprise, truly,” and added, “The fact that Merlin is the unofficial mascot of the World Cup... we feel very pleased about such a situation and above all that people love my duck.” The appeal was not just the outfit. Merlin was seen as a pet that had crossed from being a familiar part of a street vendor's routine into something much bigger, with the duck suddenly standing in for a national mood.
Then came the small test that made the joke feel real. Mexico and South Korea flags were placed before Merlin, and the duck chose Mexico. That simple decision gave the online fascination a neat answer and turned the bird into a playful symbol of allegiance, even though Merlin had not drawn much attention until recently.
The next stop is Guadalajara, where Mexico and South Korea were scheduled to play at 9 p.m. ET on Thursday, June 18. If Merlin keeps drawing notice, the duck will do what viral mascots always do best: make a serious sporting moment feel a little stranger, and a lot easier to watch.
