Not the Korean company directly but its island distributor, Sojitz de Puerto Rico. Hyundai runs second to Toyota in a car market that shrank 9% in 2025 — a strong brand, not the leader, in a contracting market. Useful context for why a small team had every reason to look for an idea that needed no budget.

May 2025, on a Puerto Rico travel forum: \u201CSpray to keep the noisy frogs quiet?\u201D The poster described overhearing a couple in a Condado restaurant discussing a spray they were using at their rental to silence the coquís, then asked how to get it, writing that he loved nature \u201Cbut my god those things are so loud at night and a little annoying.\u201D The post was later deleted.

Because locally the coquí is not noise. Alejandro Ríos-Franceschi, ecology professor at the University of Puerto Rico, put it plainly: \u201CThe coquí is not noise — it's a living soundtrack of the Puerto Rican identity.\u201D TikTok videos defending it drew millions of views and told the tourist not to visit if the sound bothered him. Then Bad Bunny posted coquí song over his track \u201CLo Que Le Pasó a Hawaii.\u201D Within days a small frog had become a question of cultural sovereignty.

The anger was there to be spent. BBDO's chief creative officer describes the mood without varnish: \u201CPeople wanted to lynch those tourists!\u201D The easy campaign was to ride it and scold the visitor — guaranteed engagement, guaranteed hostility. Agency and client explicitly chose not to. That negative decision is what made the eventual idea possible: it teaches the tourist instead of attacking him.

The question the whole campaign rests on, in the agency's words: \u201CWe asked ourselves with the client where tourists go first when they arrive in Puerto Rico. To rent a car, we answered. And we spoke to the rental companies.\u201D That is not an advertising idea, it is a distribution idea: the target — visitors specifically, not residents — self-collects at a single counter, then spends days locking and unlocking a car twenty times a day.

The factory lock-and-unlock chirp in rental cars was replaced with a real recording of the coquí. No voiceover, no explanation, no tagline. The tourist who arrived to complain about the sound now carries it on his key and hears it every time he leaves the car or returns to it. The medium is not bought media — it is a factory setting inside the brand's own product.

The campaign ran through the AVIS, Enterprise and Charlie Car Rental fleets, with printed material in each car explaining the coquí's cultural standing. The agency's EVP describes the entire build: \u201CQuick to approve and it cost practically nothing. Because alarms are dirt cheap and all we had to do was add a graphic on the cars. That's it.\u201D A Cannes juror named what moved the room: a brand \u201Ccommitted to it even at an infrastructural level, changing the factory setting.\u201D

Three things. When someone insults a symbol your audience loves, the strongest reply is not anger — it is making the offender live with the symbol until he understands it. Look for the touchpoint only your target passes through: a rental car separates visitors from residents with no ad targeting at all. And budget was neither the obstacle nor the solution — knowing where people stand was, and the fix was changing something the brand already owned.

Every number is entrant-supplied with no independent audit, and the public versions contradict each other: one reports 2.3 million reached, another 3 million social reach and 9 million impressions. Hyundai published no figure of its own. The claim that customers asked for the sound on their personal cars comes from the case-film narration with no request count and no sales number; asked on the night of the win whether that expansion had actually happened, the agency said \u201CNot so far. But that's the intention.\u201D Take the logic of the idea and the choice of medium, not a promise that changing a sound moves market share.
