To remind travelers just how important it is to bring back Toblerone as a travel gift, we launched #TantrumGirl, a live stunt at Stansted Airport featuring a young girl throwing a full-on tantrum when her mum arrived without one. Filmed and uploaded by onlooking strangers, the resulting clip took off, racking up tens of millions of views, likes, reactions, and a wave of organic user-generated content.
