Angry Birds Soda is the top-selling drink in Finland, ahead of Coke and Pepsi.
The news was revealed at the Slush conference in Helsinki, Finland, reports Thenextweb.
During a talk on stage, Rovio's CMO Peter Vesterbacka also said the branded drink would soon be available in New Zealand and Australia.
Thenextweb's reporter Jamillah Knowles said the drink tastes "fruity" and "a bit like Lilt but less sugary and maybe a bit more like apples."
Is there a category those famous Angry Birds won't fly into?
