Tikkie is turning 10. And while most brands would throw themselves a nice birthday party, Tikkie threw parties for everyone else instead. A regular party? Too predictable for Bill.

He wanted something unexpected. Something that made people go WTF. Exactly: een Waanzinnige Tikkie Feestje, a surprise party for the Groepies we all know from the app — each one with its own twist nobody saw coming.

So Bill brought in everything from a cake wrestler to a full-blown mariachiband, from Andrea Hazes to the Dikke Buiken Drum Band

It all kicked off at Wildeburg and Wilde Weide. Then WTF – On Tour took it national: Groepies across the Netherlands could win their own WTFeestje via the Tikkie App
