WWF Bulgaria Sends Fishermen a Lure That Disappears
WWF Bulgaria's SOS Rivers campaign is a 2019 direct and brand activation initiative by GRAFFITI BBDO Sofia that placed a water-soluble fishing wobbler into the hands of Bulgarian fishermen to demonstrate river pollution and drive signatures for a European petition demanding stricter water legislation.
Rivers in Bulgaria face severe pollution, with fish species disappearing at a rate that conservationists describe as a biodiversity emergency. To translate that crisis into something tangible, the campaign team engineered a fishing lure — a wobbler — with a body made from water-soluble PVA material. When cast into water, the body dissolved completely, leaving only the PLA skeleton of the lure behind, with the campaign website address embedded in that remaining structure. The gesture was precise: the fisherman held in his hands a physical metaphor for what Bulgaria's rivers were losing.
The campaign launched in Bulgaria in March 2019. Prototypes were distributed to fishermen to test in real conditions, generating firsthand experience, social conversation, and early traffic to the campaign website, where visitors were invited to sign a petition supporting stronger enforcement of the EU Water Framework Directive. The campaign integrated a fishing community outreach strategy, fishing influencers, an animated film, and a broader social media push — all oriented toward a single civic call to action. Creative direction was handled by Kiril Stoyanov of GRAFFITI BBDO Sofia, with the campaign submitted under the Public Interest category and classified as a Direct medium execution. SOS Rivers earned a Clapboard Score of 71 out of 100, reflecting meaningful creative ingenuity anchored to a verifiable environmental objective.
WWF Bulgaria chose to reach citizens through a community with direct, personal stakes in the health of river ecosystems. Fishermen in Bulgaria depend on rivers that the campaign's own brief describes as highly polluted, with fish species disappearing rapidly. By placing the dissolving wobbler in the hands of that community rather than in front of a general audience, GRAFFITI BBDO Sofia converted passive awareness into active, embodied discovery.
The strategic target was the EU Water Framework Directive petition process — a mechanism requiring a substantial volume of verified signatures to compel legislative attention at the European level. This meant the campaign needed not just reach but conversion: people who would move from emotional response to documented civic action. Distributing physical prototypes to fishermen was designed to generate exactly that chain, using peer trust within a tight community to amplify credibility before the message reached broader social media channels.
WWF's environmental campaign lineage in Bulgaria is relevant here. According to wwfcee.org, the Save Pirin campaign, active between 2015 and 2018, mobilised supporters against mass logging and construction in Pirin National Park and is described by WWF as the first worldwide successful Bulgarian environmental campaign. SOS Rivers followed that established model of petition-driven public mobilisation and pushed it into new creative territory. Competitors in the Bulgarian public interest advertising space — including Greenpeace Central and Eastern Europe's direct-action campaigns and the broader field of EU-funded environmental communications — typically rely on documentary footage and social media amplification without the product-engineering dimension that defined SOS Rivers. The dissolving wobbler gave this campaign a physical artefact that competitors' communication strategies did not replicate.
The SOS Rivers wobbler is the campaign's primary creative unit. The lure was engineered with a body constructed from PVA — polyvinyl alcohol — a water-soluble material, and a skeleton made from PLA, a biodegradable bioplastic that remains intact after the outer body dissolves. The campaign website address was integrated into the surviving PLA skeleton, ensuring that the moment of dissolution in water delivered both an emotional message and a navigational directive to the fisherman holding what remained.
Creative Director Kiril Stoyanov of GRAFFITI BBDO Sofia led the development of this execution. The design required the wobbler to perform convincingly as a real fishing lure — credible enough that experienced fishermen would cast it without hesitation — while also dissolving at a pace legible enough for the effect to register clearly. That dual requirement placed genuine engineering constraints on the creative concept, distinguishing SOS Rivers from campaigns that use metaphor only visually or verbally.
The campaign extended beyond the physical object. An animated film was produced to contextualise the wobbler's symbolism within the broader story of Bulgarian river degradation, and fishing influencers were engaged to document their own experience of using the prototype. Social media channels carried that documentation outward to audiences who would never hold the lure themselves. The result was a creative system in which the wobbler functioned as both proof of concept and media trigger: the object generated the content, and the content generated the petition traffic. Production credits beyond Kiril Stoyanov's creative direction are not publicly documented in available sources.
No verified performance data for SOS Rivers — including petition signature volumes, website traffic figures, or media reach metrics — is publicly available from named sources at this time.
What the public record does document is recognition. WWF-Bulgaria's SOS Rivers received three awards at Bulgaria's FARA advertising festival in 2019, taking honours in the categories of Social, Political, and Media Advertisement; Brand Activation; and Innovation, according to wwfcee.org. A special award connected with FARA's twentieth anniversary has also been reported in relation to the campaign, though wwfcee.org does not explicitly confirm that award was specifically designated for SOS Rivers.
Structurally, the campaign demonstrates strong effectiveness architecture even without published metrics. The dissolving wobbler created a closed loop: the physical experience of dissolution in water was inseparable from the call to action embedded in the remaining skeleton. That integration of medium and message reduced the number of steps between emotional impact and petition signature. The use of fishing influencers and social documentation extended reach beyond the prototype recipients without requiring additional media spend. The FARA recognition across three distinct categories — covering social impact, brand activation, and innovation simultaneously — suggests judges evaluated SOS Rivers as effective across creative, strategic, and societal dimensions rather than in any single register. For a public interest campaign operating within Bulgaria's market, that breadth of institutional validation is a meaningful indicator of perceived effectiveness.
WWF Bulgaria's SOS Rivers campaign is a 2019 public interest initiative by GRAFFITI BBDO Sofia. It used a water-soluble fishing wobbler that dissolved in water, leaving its PLA skeleton behind with a campaign URL, to raise awareness of river pollution and collect petition signatures for stronger European water legislation.
The SOS Rivers wobbler featured a PVA body that dissolved on contact with water and a PLA skeleton that remained intact. The surviving skeleton displayed the campaign website address. GRAFFITI BBDO Sofia distributed prototypes to Bulgarian fishermen, who tested the lure in real conditions, generating firsthand proof of the pollution metaphor.
SOS Rivers was created by GRAFFITI BBDO Sofia for WWF Bulgaria. Creative Director Kiril Stoyanov led the campaign, which launched in Bulgaria in March 2019. The execution combined a physically engineered fishing lure with an animated film, fishing influencer outreach, and a social media strategy targeting a European water legislation petition.

The SOS Rivers campaign sought signatures for a European petition calling for stricter water legislation, specifically targeting enforcement of the EU Water Framework Directive. Rivers in Bulgaria face severe pollution, with fish species disappearing rapidly. The petition strategy used the dissolving wobbler as a physical trigger to convert fishermen's emotional response into documented civic action.
SOS Rivers followed WWF Bulgaria's Save Pirin campaign, which ran from 2015 to 2018 and is described by WWF, according to wwfcee.org, as the first worldwide successful Bulgarian environmental campaign. Both campaigns used petition-driven public mobilisation as their core mechanic, though SOS Rivers introduced a physically engineered creative artefact that Save Pirin did not employ.
