Zé Gotinha was created in 1986 by artist Darlan Rosa for Brazil's Ministry of Health to promote polio vaccination for children. The friendly droplet character became a national symbol of immunization campaigns and reappeared during later vaccination drives, including Covid-19 efforts. Online, Brazilians turned the mascot into memes, and dancing edits remix his cheerful image with trending music for nostalgic humor. The joke works because generations recognize him instantly from childhood, making the silly dance version popular on TikTok and WhatsApp.
